Cowboy Shooter

Cowboy Shooter

Cowboy Shooter is a 3D Wild West runner shooter built by @pseudokid for Vibe Jam 2025. It is one of the more aggressive demonstrations of what an end-to-end AI pipeline can produce: every line of code and every asset in the game was AI-generated.

Gameplay

The game drops you into a stylized Western landscape and asks you to do what cowboys in games are always asked to do — run forward and shoot. The runner format keeps the action moving, with the player streaking through canyons and dusty towns while enemies pop up to be dispatched. The 3D presentation gives it a cinematic feel that is unusual for jam games, and the soundtrack and effects sell the genre without leaning on stock audio.

It is short, punchy, and built to be played in a browser tab — exactly the format the Vibe Jam encourages.

Vibe-coded origin

Pseudokid has been transparent about the toolchain on the site itself. The code was written using Cursor with Claude 3.7 Sonnet as the underlying model. The 3D models came from Rodin / hyper3d, the music was generated with Suno, and the sound effects were produced with ElevenLabs. The result is a game where every layer of the production pipeline — code, models, music, SFX — was generated by AI. There is essentially no traditional asset work in the project at all.

Why it matters

Cowboy Shooter is the sort of project that gets cited in arguments about where game development is going. It is not the most mechanically deep game on this list, but it is a complete vertical slice of an AI-only pipeline: prompt-to-engine, prompt-to-mesh, prompt-to-music, prompt-to-voice. The fact that it ships and feels coherent matters more than any individual mechanic. Listed at aibuiltgames.com as a flagship example, it is a useful reference for anyone trying to map out what a fully AI-powered game pipeline looks like in 2025.
