Getting the Blue Key / Getting to the Blue Key Slots

Start in the parking lot outside the building. Grab the Shotgun Shells behind you and the Chaingun Cannon in front of a barred window.

As you approach the building, a car crash and chaos will occur, followed by an assault from a Pig Tank. Defeat it.

Collect the Pipebombs and a Large Medikit from the side of the parking lot. Note that the manhole cover (press the cover button to crouch behind walls or objects) nearby can be destroyed for later access.

Find another Large Medikit near a lamp post at the building's entrance.

SECRET 1: Requires a Jetpack. Jetpack up the building to a window with graffiti underneath. Enter to find the secret, a Freezer, Steroids, Microwave Expander Ammo, the Devastator, and an RPG behind a desk.

Enter the L.A.R.D Building. Be cautious of another Pig Tank in the entrance.

Gather Shotgun Shells and Body Armor from a couch, Chaingun Cannon Ammo near the phones, and a Large Medikit on a counter near the car.

Proceed to the stairs at the far end of the entrance. Two Pig Cops guard the top of the left and right staircases.

SECRET 2: At the bottom of the right staircase, hit a switch and run to the phones to get an Atomic Health.

Ascend the left staircase. The second room on the left contains an RPG. The third room on the left is open but hides a Pig Cop behind the door.

Enter the Offices and be attacked by an Enforcer. Turn on the light switch near the door.

Find a Portable Medikit and Shotgun Shells to your left. In the offices beyond the bookshelf, the farthest one contains Night Vision Goggles and a Small Medikit.

On the other side of the bookshelf, defeat four Pig Cops, ideally with a Pipebomb. A window here offers a view down to a lower room.

Drop into the room below. You will be attacked by a Pig Cop and possibly an Enforcer from the computer room.

In the computer room, two more Enforcers await. A Commander will spawn in the previous office area and attack you. Steroids are located on top of the computers.

Exit the computer room and proceed right. A Pig Cop will attack, followed by an Enforcer emerging from the darkness.

The Blue Key is at the end of this room. Go up the ramp, grab the RPG Ammo at the top, and use the Blue Key.

Using the Blue Key will open all previously locked Blue Key doors. Exit this room and proceed down the ramp to the Security Access door.
