Elevator banks. About ten elevators, in a L shape. One elevator opens, to reveal a single Replica. Yeah, I blast his ass to kingdom come. I am wise to the tricks of the Replicas though, so I dash to the end of the banks, and hide behind the corner.
Ding. The light of the elevator spills through the opening door, right next to my hiding spot.
"Recon." Their officer barks.
Hehehe, you poor, stupid bastards. I wait a moment, then turn the corner, activating slow-mo. Two Replicas right next to me, both facing the wrong direction. I melee them, killing them both with a single swing. I open fire, pumping two shotgun shells into the tightly grouped pair of Replicas past them, killing them both.
Ding.
Oh shit.
The elevator directly in front of me swings open, to reveal a Heavy Armor Replica, and three friends. They react fast, but I am far faster. I toss my last two proximity grenades randomly in the room, and dash behind cover as I gun down one Replica. I switch to the HV-Penetrator, and spring around the corner as one mine explodes. One head shot finishes the final basic Replica, then I pump the rest of the clip into the Heavy Armor Replica's abdomen, chest, and head. He doesn't go down, so I pop back around the corner.
Boom. Hehehe, proximity mines are great.
