Monsters and teleporters
The creatures appear in large numbers and press in on your character from several sides. The teleporters play a special role: as long as they stand, more enemies can break into the facility. Hunting down these facilities is an important part of the missions.

Survival mode
Besides the campaign, you can test your endurance in a separate survival mode. Here, the goal is to hold off repeated waves of attacks for as long as possible. New weapons and upgrades become important outside the main missions too.
