You (and your team) have been contacted to cause a meltdown in a refinery. Once you enter, choose one of four different classes (Medic, Engineer, Scout, Sniper) each with their own strengths, weaknesses, and combat loadouts. Use teamwork to work your way through the facility and place the four power cores needed to cause a meltdown. Once the four cores are placed, escape within the time limit. All of your team must make it out alive, or none of you will.
