Overkill 3 is a pretty enjoyable third-person shooter that was sort of begging for some online multiplayer. Fortunately the begging can stop, because its newest update has added an online co-op mode.
Now you can play online with friends or strangers while working together to shoot badguys in the face, and you can talk about your victorious face-shooting in the game's new open chat room. If that's not enough you'll also be able to take part in various 2-day tournaments to earn prizes and collect special callsigns - callsigns that, of course, can be show off in your new online profile while you brag to prospective new gun buddies.
Overkill 3 is available as a free download, and you can grab the co-op update (co-opdate?) now.
