There will be seven multiplayer modes but only four of them were discussed at the event:

• Deathmatch: Supports up to 18 players, with the goal being to rack up the most kills.   
• Infestation : This pits a squad of marines against a single-player-controlled alien. As each marine is killed during a match, he will respawn as an alien until there’s just one last man standing.  
• Predator Hunt: This is where you get to play as a group of predators hunting a sole alien. You’re given a short match time of three minutes in which to kill the xenomorph and rack up the most kills on your team. 
• Survivor: This is the updated Skirmish mode where you’re going after wave after wave of increasingly different and difficult Alien AI. You can do that in a four-player co-op.
