First-person shooters
Saltline
The most polished single-player FPS here. You are a breach unit dropped into a container terminal at dawn, and you have to cut three uplink relays and reach the boat while robot dogs and drones close in. WASD to move, mouse to aim and fire, R to reload, Shift to sprint, C to crouch. Phones and tablets get touch controls. Anthropic engineer Felix Rieseberg made it to test Claude Fable 5.2 with a single prompt. The level is short and heavy, so lower the quality in Settings if it stutters.
BODY-CAM
The closest in tone to a modern military shooter: everything is seen through a police officer's body camera as your squad serves a warrant and clears a house room by room, with calls of "Room clear" and "Tango down". The maker has added 5v5 multiplayer, and it plays with keyboard and mouse or a controller. It is the most-played game on the AI game maker Tesana, with more than 9,000 players.
Brasidas
Big team matches like a Call of Duty ground war, but in a Halo-style setting: two teams of ten fight Big Team Slayer on a ring world, with rifles, a sniper scope, a kill scoreboard and a leaderboard. It was made on Tesana with a few prompts.
Gilt & Gutter
A short 1v1 first-person duel in a golden hall. Shots that match your coat colour charge your gun instead of hurting you. Kevin Ngo made it with Claude Fable 5.2.
VibeGaming.top
Started as a vibe-coded FPS parkour game and grew into a hub of more than 22 browser games made with Claude, Cursor or ChatGPT. Come for the parkour shooter, stay for the rest.
Other shooters
Crimsonline
A top-down 2D shooter in the style of Crimsonland, for one or two players, with an endless Survival mode and a ten-level campaign. Hundreds of monsters come at you at once. You can host a room or play solo. If Zombies is your favourite Call of Duty mode, this is the nearest thing on our site.
A Crimsonland-style shooter with hundreds of monsters at 120 fps, even on phones.
Skyfall Protocol
If you like the jets more than the guns: fly an F-22 over a photoreal copy of Lyon in a WebGPU air-combat game.

Is there a Call of Duty Zombies browser game? Not an official one. Zombies is a mode inside Activision's Call of Duty games. On our site, the closest thing is Crimsonline's endless Survival mode against hordes of monsters, which is a top-down 2D game, not a first-person one.
Can I play online with other people? BODY-CAM has 5v5, Brasidas has 10v10, Gilt & Gutter is a 1v1 duel and Crimsonline lets you host a room for two. Saltline is single-player.
