The four new multiplayer maps are:

1. Bullet Marsh: In this Kryll-infested swamp, an old generator still powers the area lights. A few stray bullets could easily knock out the generator, leaving combatants to fend for themselves against the Kryll.

2. Garden: This overgrown and crumbling conservatory still has a working fertilization and pesticide system. This system can pose a serious hazard to anyone who ventures into the greenhouse without first venting the air.

3. Process: Teams must fight for control of this subterranean Imulsion processing plant, still active despite the cessation of the Pendulum wars.

4. Subway: Timgad’s Central Subway station used to serve as a central hub for commuters. Now the tunnels are crawling with Locust.
