1. Turn on power

Power Part Locations (2 parts): Lever is on the floor in the starting room by Quick Revive. Power machine part is laying under a ramp leading to one of the puzzle rooms. Build power next to Jug.

You will need a key card to unlock the power room. The key card is found in the room with the 3 robot turrets. You will need to throw a grenade at the wall with the grenade icon and inside will be a desk with the key card.

2. Shoot all of the display panels that are hidden around the map. They will make an electrified noise once they have been shot. Some can only be reached with grenades but they aren't very hard to find. The last panel will give off a different electrified noise indicating that it was the last one. Once you find and shoot all of the panels, the elevator at the bottom of the map will open up and you can then spend 15k points to leave.

Free Perk Reward:

1. Go to the room with Staminup and hit/shoot the painting on the wall. Take the key behind the painting.
2. Go to the area where Pack-A-Punch is at and find a door where you can use the key. Inside is a cube and a wall buy for a crowbar.
3. Take the cube and go to the large grassy area with all of the broken robot machinery. Go to the pipe in the ground at the back and put the cube inside. You will then get awarded a free perk.
