The game starts in the room where Hank (in his MAG-form) wakes up and escapes from the Agent Magnification Chamber. On the floor lays the corpse of Deimos. Also in this room, you are shown some of the game's controls. In the next room, he meets Sanford. In the following outside area, the protagonists fight with a Mag Agent: V3 and the Auditor. After winning over the Auditor, he creates the rock on which he flees. A door appears, leading to several rooms where grunts, l33t agents and A.T.P. engineers are encountered. After your victory, the Auditor absorbs Tricky and explodes.
