By 2020, decades of escalating international terrorism — from Oklahoma to Tokyo to Berlin, Lagos, and finally a chemical attack on Hawaii — forced the formation of the Multinational Peacekeeping Executive. The MPE operates with UN member nations' collective approval to deploy directly against terrorist organizations anywhere in the world, bypassing the delays of negotiation. As an MPE operative, the player faces some of the best-equipped terrorist organizations and most dangerous strategists ever assembled. The mission is to keep fighting, not just for survival but for humanity as a whole.
