How to Make an FPS Game

In this video, we build a first-person shooter using ZTRONICA. The FPS genre includes some of the biggest franchises in gaming history, from Call of Duty and Halo to Counter-Strike, Valorant, DOOM, and Borderlands. We implement a first-person camera rig, smooth WASD movement with mouse look, a shooting system with raycasting and hit detection, basic enemy AI that patrols and reacts to the player, a health and damage system, ammo management, and a game over screen. ZTRONICA handles the complexity behind all of these systems through its AI assistant, which generates the 3D physics, camera controls, and enemy behavior from simple descriptions. Whether you are inspired by the shooters you grew up playing and want to build your own, or you are curious how FPS mechanics actually work, this tutorial gives you a fully functional foundation to build on.
