Sauerbraten Summer Edition is an ego shooter that was created with the Open Source engine Cube 2. The game features single- and multiplayer game modes and looks incredible if you consider that this is an Open Source project and not a commercial one. The single player part of the game reminds me a little bit of games like Serious Sam and the original Quake games.
Unbelievable Ego Shooter that plays in Browser
This game takes browser games into the next level. The deathmatch maps that are currently playable feel and play a lot like quake 2. You always play against a handful of bots using well known weapons like the rocket launcher or the minigun. You can pick up health packs and med packs, this is fun. Phosphor demands the newest shockwave plugin, you will be redirected to the download site if you don´t have it already. Take a look at the screens and head right to their website.
