TuT How to use the pack a punch

[uzi]

Located around the map are 4 player activated pressure plates with a monkey face/skull on them.

I was playing with a friend so we only needed to activate 2 at one given time.

As I said there is 4 of them: Right near the power activation, At the spawn near quick revive, the right side of the bridge over the water fall.

4th pad location: At a cave in on the tunnel down underground where the box is that shoots you up to the railcart.

Players need to be stood on these pads at the same time for the stairs to raise to the pack a punch.

You get about 1 minutes use out of it before you get thrown down the stairs.

Sorry, I just haven't seen a tut like this.
