Walkthrough
Pick up the large ammount of supplies and head into the arena flanked by two large cages of bad guys, many of which will teleport down to greet you. Press the switch on the small tower at the opsite end of the arena to raise stairs up into the cages where you will find the red and blue keys.

Climb the small stairs back near where you entered the arena up to the blue and yellow bars. Open them and press the switch behind them to lower the cages revealing a number of bad guy's behind them.

Head to the top of newly exposed area on the right to find a small alcove containing a teleporter which will take you up into the small tower. Jump off the tower and a wall will open in front of you, behind which is the red key. A Cyberdemon and couple of Arch-Vile's will teleport into the arena once you do.

Head to the top left of the arena to find the red bars, behind which is the exit.

Secrets
1. In the left of the start room is a small secret containing a plasma rifle.

2+3. Up behind the blue and yellow bars, one will find a med kit half embedded in a wall. The wall is a fake one and can be walked through to a small alcove overlooking the arena. There are no items or power ups here though. There are two secret sectors here, one imediately behind the fake wall and the other is the actual alcove.
