Helmet, FlashLight and Headset added for all marines (including the mercs). New MP Mode: Coop (play like in the movies with your friends). This mod implements several multiplayer features unseen in current modes. Of all the multiplayer modes currently available, this modification will definitely add a more involved, team-based mode of play.
The X-Coop mod was created in order to enhance the Aliens vs Predator multiplayer experience.
