You were at the base checking the weapons as suddenly the alarm goes off. That can only mean one thing... The enemy is here.

You jump up, grab a gun and run out to the corridor. You turn your head just in time to see two heavily armed soldiers shooting one of your teammates. From their look it could be the so called Ghost and Gaz but you could be wrong. That would mean that TaskForce 141 somehow got in the base. Not good... As your fellow solider falls to the ground they look up and see you.

They exchanged a quick look before coming your way. You turn the other way and take of running, keeping a firm grip on your gun. Your new objective? Survive.
