Unfortunately, they offer damn near no information on the game. We do know that the main campaign will be focused on Marines, but there isn't anything stating whether or not you could play as Aliens as well. It seems to be focused on customization for your marine; you have loadouts, you have experience that earns you perks and you have weapon customization. One awesome feature is cooperative mode, but it isn't some half assed coop mode, it's fully involved. At any point during the single player campaign you can call in your friends to assist you and the entire campaign can be played cooperatively with four players. They are also try to make it a seamless drop in/drop out cooperative mode, meaning that at any point players can enter and exit the hosts game. Other than that information, there isn't any available to the likes of me, sorry, but there is this exciting new trailer. Thanks for reading and hope someone else is a little excited about the prospects of Colonial Marines.
