John Wowcool has released [*One More Bullet*](https://sbox.game/wowcoolgames/one-more-bullet/?ref=killscreen.com), a one-shot arena shooter, on s&box, the game platform from *Garry's Mod* developer Facepunch. Made under the WowCoolGames label for s&box Game Jam III, whose theme was "One More Round," it is playable now through s&box. Watch [the trailer John Wowcool posted to Instagram](https://www.instagram.com/p/Ddu4rYpsd3o/?ref=killscreen.com) below.

The player carries a single bullet in a small revolver. A kill returns the bullet, and a miss ends the run. Each retry generates a new layout, the monsters multiply and speed up as the kills add up, and a boss arrives at 45 seconds. The package page lists 12 creature types, among them a Grin Runner that pounces and a Trip Anaconda whose body can be shot anywhere, in an arena of face-covered walls, liquid metal and a shifting rainbow sky.

The game has since added two online modes: co-op for up to four players, and a one-on-one versus arena where the winner keeps the spot and every fourth match opens to four fighters. It keeps public leaderboards for score, kills and survival time, and offers settings for reduced flash and reduced motion. Its asset notes say the game uses AI-assisted code and that some supplied artwork is AI-generated, alongside procedural Blender models and synthesized audio.

Facepunch pitches s&box, built on Source 2, as open source with no royalties. The jam's final four, announced Sept. 29, were *GAMMA TEAM*, *RUN IT AGAIN*, *Catz VS Ratz* and *Keg Quest*.
