Prelevel6 background_6 A.I.M. Vault - Level 4 clearance only! A.I.M. Vault - Level 4 clearance only! This place is starting to give me a major headache. They locked the keycard in the room across the way. I need to get there and crack that code. You shouldn't be down here! We told you not to come down here! You must find the key to turn off the force field. There is a portal over there that might lead someplace interesting. I just need to take out these mechs. To survive this pit I need to time the platform jumps.
