Build a Mobile FPS Game with AI and Unity MCP Toolkit

Guys, I'm going to download a few animations from the Mixamo website. Then, I'll find a low-poly first-person

shooter kit for mobile. I'll get a game engine, and finally, I'll give all of this to AI and tell it to build a

mobile game for me. The AI easily sits behind Unity, my game engine, like a professional developer, and using the

assets it has, it gets the job done; this is a revolution. Today in the game industry, something that used to take

humans hours to do, even just understanding the kit's mechanisms, now happens in seconds, and that is exactly

what we're teaching in this episode: connecting LLMs, AI, the game engine, and a ready-made kit, all together to

build a top-tier game. Stay with me. Well, my dear friends, our recipe for building a game: first of all, you need

to download a game engine. This time we're going with Unity. I'm using the " Lantern" VPN because games require some

downloads, and VPN costs are not cheap these days; this free Lantern finally worked, and we'll move forward in this

course with it. Obviously, tools work differently in each period; I mean this VPN might not work later. I'll search

for "Unity Hub download" on Google, and first, we'll download the Unity Hub; it's like Unreal Engine (maybe Godot

doesn't have a hub); these are all game engines. In this section, it has options for Windows, Mac, and

everything else; all versions, even Linux; don't let it confuse you! Click on "Download Unity" here to first get

its Hub. You can also ask the AI for the address. Connect to your Gmail to create an account. And you'll easily

see that you're directed to a page that asks: "What do you want it for now?" Do you want it for Mac, Linux, or Windows?

Well, I'll download the 64-bit Windows version, and this is how the Unity Hub is downloaded for us. I think it's no

more than 600 or 700 MB; it starts from the Hub, and then the engine installation itself is under 200 MB (

today its size is 200 MB). Well, the download is complete. I'll install the Hub; it wants to take up about 600 MB

on the C drive. The Hub itself. I click "Next" and let the Hub install. Now it asks if I want to run it. Yes, run the

game engine—well, not the engine, the Hub for me. It has a license or terms page; scroll it all the way down. This

means we've read it completely, and then click "Agree," which means I confirm. Well, here you just need to

click on "Create Account." Since we linked it to our Gmail account, it syncs quickly. Look, it says open the

app. It opens the app, establishes a connection, and essentially creates an account for us using that same Gmail.

Wait for it to sign in and enter. This is advertising one of its tools; just hit the X, we don't need it. In this

space, which is the Unity Hub, guys, it says down here that no editor is installed; you don't have any engine in

the Hub space; and it's right. Don't worry about this. On the left, look at the Projects, Templates, or Installs

menus at the top. From the Installs menu, we can easily install a new version. Click "Install Editor," and

then it asks which version; today, as you can see, we have the Unity version. When I was recording the game

development school tutorials, if you recall, I was working with Unity 4. Now , this week, for those who have a

subscription to the game development school on my website, I want to add a series of updates regarding this MCP

topic, because there's a lot of demand for it. You want to connect Artificial Intelligence to Godot (the Godot game

engine), to Unity, or to Unreal Engine. I told "Barsha" to create a comprehensive tutorial on all of these

so we can cover them for you guys. I am teaching you Unity in this section. Okay? As one of the game engines, it's

clear that the latest version is here, and today I'll set this one to install. If you want to get an Android output,

as I said before, check the Android build kit; if not, you can add these later, so don't worry at all. Just the

main part, meaning installing Unity itself, is sufficient. The problem is, it says this is 9GB, but you have less

than 8GB of space left on the C drive! Okay? Okay, if it happens like this, go back to this option, the Install

section, set the installation path to D instead of C, have it go to D, for example, a folder named Unity, and

install it there. Done. Install; here it says you have enough space, so continue. This should go ahead; of

course, make sure to check this box, read the terms, and click install. That's it, it should now go and

download these nine gigabytes; 9GB needs to be downloaded. Well, it's done ; Unity is a relatively lightweight

engine, or at least has the necessary extensions; now it's installing and downloading, and we don't have anything

else to do with it for now. From the Projects section, we set up a new project. I'll teach you how you can...

though it currently says you don't have a license, keep this in mind. Click on this option; if you have a good VPN,

the license will be issued easily. If not, know that it's normal—keep trying different VPNs until it grants

us the license. So first get the license, and then [click] "New Project. " Through this option, you can easily

create a new project. It asks whether it should be 2D or 3D; how should I set it up for you? The engine handles all

the base conditions for this. I'll say, "Look, for now, I want a 2D game to go into, for example, that folder on the D

drive, the 'Game Dev' folder." I create a "Test" folder, "Test 1," and have it sit there; the project will run there,

for instance. I click "Create Project," and you see that you don't need to worry about the rest of these

checkboxes. You see that easily, well, Unity creates a project for us. In fact , in this game engine, we are creating

a 2D project. Okay, so that's that; this is how we can create a project in Unity, and now I want to download a

ready-made kit, as we want to add the kit there. We create a project first and then import the kit; that's why it

was necessary to learn how to create a project. Well, I think let's go ahead and find a decent kit. I told you

everything needs to be together: the game engine alongside a kit that contains the necessary assets (is rich)

, and an AI generator to put everything in its place within the game engine for us. I type "Unity game template" and

The official Unity website itself, the "Unity Asset Store," is full of templates, mechanisms, and ready-made

kits, many of which are free, while many others are paid. This is actually a source of income for people who

prepare assets; it means they are helping an independent game developer. When you are an indie game developer,

just one person, it's clear you use these assets so the project moves faster and to compensate for the lack

of manpower. For example, look, in the "Free" section, there is a "Free Template" here, and we have to see what

world it aims to cover. I found a low-poly shooter kit a few days ago— something like CoD but low-poly with

very low graphics for mobile—and I thought it wouldn't be bad for this tutorial. I saved it in my library;

inside it, you can save anything you find to use later, for example, and download it when you're ready. Look

here, in the top section, under "My Assets," there was this free Poly Shooter kit; I added it, but I haven't

added it to Unity yet, I just kept it here to teach you now. I’m opening Unity again, this time for a 3D style,

a 3D project. I’ll specify the path and put it in a different folder so it doesn't go into that 2D game we made, I

mean the project we ran. I’ll name it "Shooter," ignore those two checkboxes as I said, click "Create Project" and

wait for it to build a 3D project; this time the engine is preparing to build a 3D game, that’s why it takes time.

Okay, this is a 3D project; now for the kit I had in mind, you can see it from the top option, Window, here look at

Package Manager, you can also call the Store this way which actually takes us back to that same website, and here I

told you that in my stuff, I’ll provide the address for the third-person shooter kit so you have

the same one; if you want to practice with me, open this and click "Open in Unity." Now it’s actually going into

our Unity, wanting to download; see, it says 44 MB here, but it hasn't downloaded yet, the download option is

here inside my Unity, and I click the download button so it starts downloading, starting the download for

those 44 MB. It has a good speed even though I'm using a VPN, and it’s done ; okay, for now, these are the project

details, it has downloaded, but I still have to click "Import" to add it to the project we just created. The 3D project

we were just working on. The project is raw, this option came up, click "Import " and ensure everything ticked here,

every option listed here, is checked and enabled. See, keep it exactly like this. Click "Next" then "Import" again.

It says there are some issues, I don't have these. Okay, go ahead and download it, do whatever you need to fix it, and

run the project—I mean the ready-made kit—for us. Wait a little while for it to resolve the package issues. Now

see, it's ready; why do I say it's ready? Because we have its files right here. It has now come into our project,

into the 3D project we just created. I'll close this, this window; and in our 3D project, see where it is in

these folders? Aha, it's called Infima Games; it's this first folder, Low Poly Shooter Pack. I'll enter this folder,

we have the scene here, and if I run this, the project executes, which is a ready-made kit. Let's see what it

actually is and what capabilities it gives us. I'll play the game; The kit wants to showcase its capabilities in

this space. Okay, it says this is my graphics; it's good for mobile games, good for low-poly games. Let's go in

front of it, see how many guns it provided, what's what? Its shooting and aiming system is good too. This kit,

it's a very famous kit. See, for example, if we want to create an explosion, it gave us samples here;

it's good, it's cool, we'll just use these. Now, I'm the AI, actually, I'll be using these. What else has it given

on this side? It provided a series of textures, I think, for the gun. Aha, you can also change the gun. It's

included a few gun variations. It even added a pistol. Well, that's good. It has provided some very cool things. I

like it, bro. Well, what's going on in this room? A series of elements for— ooh, that explosion was cool. I said

it's a very famous kit; many games have been built and customized with this. Another explosion style. A series of It

looks like gas; first, such an animation plays, then it explodes. Well , you can do interesting things with

these, and this kit, well, everything is ready, the logic is set so we can quickly customize it; for example,

download another map and move this kit into that map, and we shouldn't do this ourselves today, let the AI do it. That

is actually the topic of this session, and the interesting part is right here. So Now we have the engine; we have

installed the engine, and the kit, this is a unique kit for making mobile games . Let's move to the next stage of

connecting our game engine to the AI via MCP so it can use these assets; use this ready-made kit for development.

Well, in this session, I want to use " WorkBuddy" as an agent, as an actor, through which we connect to Unity. I

said with MCP, we'll get the job done. You download it; I provided its Windows version, I taught it; from zero to 100,

I even taught you how to connect providers. We use this method, this technique of having an agent write code

for us, in web development as well. So you can find interesting content there too, on the Web channel; especially

finding a free provider, which is simultaneous with this tutorial, We also talked about free providers on the

Web channel, which you can go and watch . Well, first I'll give it the project address; "the game dev shooter" should

come here and sit in this corner folder . Okay agent, now the model we choose, the DeepSeek "V3-Flash" model, which is

free, comes in handy here. More powerful models are paid and more demanding, but in this example,

you’ll see that DeepSeek V3-Flash is a genius. I tell it: "In the folder you are sitting in, there is a Unity

project, and I first want you to connect to Unity via MCP; MCP is one of those standard protocols that creates

the best possible conditions for you." It’s as if it’s sitting right behind the software and has access to

all the tools. It sees all the files and, well, moves the work forward more easily. I’ll wait. Look, there are a

hundred official and unofficial Unity MCPs; But I told it to go search, find them, and see which one is better for

us and has no issues. After all, we want a standard MCP to connect to our Unity, and this is the best possible

condition and the best possible method. My dear friends, I’ll wait for it to do its job. Well my dear friends, it

finished its task; it ran into a problem mid-way, saying you don't have enough free gigabytes, there is no free

capacity on your drive, should I delete such and such file myself? I said: "No sir, let me take action myself."

Finally, I cleared a gig for it, and it restarted the task and said the connection was established and now we

are connected. Okay, if we are connected, it means any change we want to make in the game, this same agent

can apply the changes and easily push the work forward. I said it's like a colleague sitting behind the system

trying to get the job done. Of course, it's better to read its explanations in every response. For example, it says

here to fix the issue through this WorkBuddy via its contactor. It has provided it for us again down here. It

has explained it step by step. It means click on this option, go through the Contactor Manager, and select Custom.

Activate this for me here. Okay, allow it to connect to Unity MCP as well; the tool requires this and it had already

explained it to us. We have done the work now, and I can tell it; I can tell it that I have done what you said and

the task is fixed correctly. It told me to hit "Trust" so I can get the work done. I'm telling it: "I did what you

said, I want you to explore the project ...so you gain enough understanding of what I'm doing, what's what, and how

that shooter kit is supposed to work." Well, after a few minutes, as you can see, it has performed the analysis and

clearly identified everything—what relates to what and where exactly this shooter kit is used. It even found an

issue; it says there's a problem somewhere in the shooter kit, and there are some assets that are...unused and

just sitting there; we can use those too. It now has a full, sufficient understanding; thanks to this MCP

standard, it has gained enough grasp of the project, and it's enough to take whatever action we want at this stage.

Well, I want to add a map. A series of characters as enemies to attack us, have some logic, and it's clear that it

can easily do all of these things. Let's start by finding a map. I mean, we want to change this base environment

, right? This is the kit's own environment; we'll enter the same Unity website again to find some free assets.

I've already picked out a few assets like a low-poly character and a low-poly map, and I'll give you the

links later. Again, in the same way, the same way we added this kit, I'll click the download option for each one

individually; meaning, first I hit download to get them, and then I add them to the project. The rest of the

work is in the hands of the AI. Once these are added to the project, I'll tell it: "Look, now you have some

low-poly characters and a complete map; so apply the changes exactly the way I want." I added the character and the

map, I'm adding the characters too, and now all of these—both the map and the characters—are inside my Unity

folders. Look, this is the character, actually, and this is the map. Okay, see, for example, let me open it; now

we go into this map. Well, let's go to the agent and tell it what we want. I'll tell it that I've added a map to

the game; it can easily understand— I'll even write the map name for it so it knows what I mean. I want this scene

—I'm telling it that I want this to be my main game scene; to be my main map and for the game to start from here

now and. Along with that, now I’ll give you a low-poly character; I'll copy the name exactly, the file name or

the name of this folder, and tell it, " I've given you this too; write the mechanism for me where this enemy

attacks us, and we can hit the enemy, using the kit, but in the new map environment I've given you." See how

this can work miracles! It asks me a few more questions; read these carefully, I'll answer its questions

about how my game mechanism should be, and then it goes to coding; it might even take hours. Well, in the meantime,

while it wants to do its work, I'll go to the Mixamo website, Adobe's famous site for ready-made animations. Because

during our talk, it was telling me: " Sir, we don't have animations; if the character falls and dies, well, we

don't have death animations for the enemy, or for example, shooting; should I build these myself?" I'm logging into

my Gmail account on Mixamo; I have a complex task, I don't let the kid...its AI said, "Should I build it myself or

will you give it to me?" It's obvious I'll give it to it; it's useless if it builds it itself. Inside Mixamo, I'll

download a series of animations from here and tell it: "Come and rig these animations to the enemy character." On

these, for example, look at this one; now the animation name is "Basic Shooter," whatever it does, it has a

gun in its hand, it shoots, it even throws bombs. A series of these same animations, look; I easily click on the

download option, let it be T-pose, this could also be FBX; it’s no problem, and it's downloading. See how much the

world has changed; before, we had to bring the enemy model here, it would do the rigging, it was a strange ordeal;

but now I just downloaded the animation , and I'll tell the agent again, "Sir, here is the animation; place it

wherever it's needed." And this is why I say strange things are really happening in this field; it has saved

so much time, and even an amateur today can sit down and create a game. Well, I tell it about the different animations,

that I put a series of animations in such-and-such folder; I tell it the folder name, "New Animations," and tell

it to extract and use them. Wherever it is needed, wherever it makes the game look smoother and more attractive. I

tell it the enemy must have natural physics. The walking animation, idle, I’ve given you everything, so go look

, find it, and match it. Okay, it goes to think and analyze again until it wants to deliver the work to us, and we

can proceed in this way today. The work is finished, guys. It has created a series of images; it’s incredible!

With that same low-poly graphic and the same map we gave it, it took the character into that map. Let's go play

it; just see what a blessing this is! I mean, how strange is it? Well, we went into that map, the map we downloaded;

there are a series of enemies attacking us. Do you see? It even added the gun's recoil; I really liked that. You might

say the AI or enemy intelligence isn't very good; it's confused! Okay, it can be upgraded, or we can prepare a

separate kit based on smarter enemy AI; for now, they just see us and shoot in our direction, which is great. The

blood effect, I don't even know where it came from, it decided to add it itself; it's incredible, incredible,

incredible. It's very strange to me, the novelty of it never wears off. The more we build and move forward, I'm the

first one to be surprised. Well, that's that. This could be a mobile game. We can continue like this and design more

levels. In such cases, you might want to design the level manually. Meaning, you download another asset. An asset

that gives you all these walls, and you might want to do the wall placement yourself, or anything else. If you look

at the game's mechanics, it's not very complicated right now. I definitely have to show you the NavMesh. Yes, it's

a space where your character can move around. As you can see, only your character's hands are visible, meaning

it's first-person; unless you change the character. This blue space you see means the character can move there; so

a space for character movement is considered in the mechanism or the backend of the story. You have the

player, you have the lighting system; this mechanism is interesting after all . Understanding what the AI has done is

important for you; it's not just about the AI doing it, but what exactly has it done? Where did it mess up so I can

tell it to compensate? For example, going up these stairs isn't possible right now; because the NavMesh isn't

connected to the stairs, so the character doesn't go any further. For example, you see things like this; that

was the blue floor space I meant. Well, that's enough for the first session, my dears. My main intention was that we

are connected to Unity via MCP, and I said that in the updates for my game school, I will also add MCP for Godot,

which is very popular, and MCP for Unreal Engine. Thank you for being with me this far, ask if you have any

questions. I love you all, until the next tutorial.
