Scheduled for a May 27 release on 360 and PC, Colonies mainly adds new, creative multiplayer modes to the original game. Several are based on holding checkpoints and CTF variants. Our favorite, however, lets one gamer control an Akrid, with the others teaming up to try to take down the alien. Different creatures are available, and we recently saw a demo showing how a spindly, player-controlled giant can make quick kills with its swiping legs.
New playable characters, new weapons, and new levels are also added. Many of those are tuned for these alien battles, giving bunkers for humans to hide from the less-mobile aliens. Xbox 360 and PC players can play against each other using paid, Xbox Live gold accounts. Non-paying PC gamers will still be able to play online, but they'll only face other PCs.
