Mission Against Terror
New 4 Player Co-Op Mode
June 11, 2013 - Suba Games

We've finally added in a 4 player Co-Op adventure in our efforts to expand the gameplay of Mission Against Terror. Dodge traps suspended over lava pits, or rolling mountains of snow as you fight your way through the Snake King's temple on your way to victory!
