Combat Online Game

Combat Online drops you into a blocky, voxel-style arena against players from around the world. It's a first-person shooter built by NadGames as a follow-up to their earlier hit Combat Reloaded, and it keeps the same pick-up-and-play feel: no downloads, no launcher, just a browser tab and a gun.

Matches run across a rotation of small-to-medium arenas, with a handful of modes to choose from — free-for-all deathmatch, team battle, and capture the flag. Weapons and movement are simple enough to learn in a round but the blocky maps have enough sightlines and corners that positioning still matters. Players who want more control can also build and share their own arenas in the game's built-in map editor.

Controls

• WASD — move
• Mouse — aim
• Left Click — fire
• Number keys — switch weapons
• Space — jump

It suits short sessions — the kind of shooter you load up for a few quick rounds rather than a long campaign, and it runs entirely in the browser with nothing to install.
