Level 2 Unit 3 - The Detention Center

Goal here - locate blue key-card.

U3L2W1 (strategy)

Collect health and ammo while destroying Gunners on each side of you. Enter this room, kill the Enforcers, and proceed outside. Be careful - there is a tough Tank out there! Jump back in the hallway for cover and blow him away!

U3L2W2

Scoop the bandoleer and health, then continue along to the left since you can’t enter the large doors without the blue key. Enter this room, kill the opposition, and snag the blue key beside the computer.

U3L2W3 (strategy)

Enter the previously restricted area and now you must locate the red key in the security complex (level 3). Before that, so straight onto the platform, killing everything in sight and then drop down to the level below bare you to grab the chain gun. 

U3L2W4

Back in the outdoor area, enter the trapezoid door without the red square in the corner (you’ll need the red key for that). This is the jail area for humans. Open up all the cells by hitting the buttons on the outside walls, and grab any power-ups you can use. Watch out for Enforcers above you. 

U3L2W5 (secret)

Exit the way you came in and turn left to find a quad damage protected by red lasers. Travel even more left and you’ll find a nearby button on the wall to de-activate that. Walk up the stairs behind you and turn around immediately to take out the Gunner. There is a glowing yellow button on the wall behind him - shoot it to extend the stairs up to him. But you don’t need to ruin up the stairs to grab the ammo just yet - instead drop through to the prison cell area. Turn left and exit the door near where the quad damage. Turn left again quickly to enter a secret area under those stairs with combat armor in it. 

U3L2W6 (secret)

Now proceed through the jail cell area and press the button the wall directly in front of you. Kill all the enemies here and enter the barred-off room in the middle. This is how you accomplish this - press the green button and enter in the room where you’re allowed to go, then press the button on the wall on the inside and leave toward the right. Press the button near the jail cell area again and you’ll be able to enter a door on the left to get inside. Here you’ll find an adrenaline, bandoleer, cells, and health. This is the last secret for the level. Now enter the room where the Tank was, which will be the level 3 - the Security Complex (please see “Level 3” in the text until you need to refer back to level 2 again).

U3L2W7

Head straight out to the outside and enter the door with the small red square in the corner. Kill all the enemies and then enter the door to your right. Take the left up the stairs to scoop up every health pack, ammo, armor, an weapon available on that ledge. Enter the door while up there and throw grenades down to kill the Strogg below. Cruise down to get the health and a grenade launcher in the prison cell. Walk back up  but watch out for the Enforcers  - they’ve now broken through the wall when you grabbed the grenade launcher.

U3L2W8 (strategy)

Enter the small door to your left and back down the stairs. This time, turn left and head down the hallway, killing all Enforcers in your path. Step on the platform, which will take you to the yellow laser security computer. Turn around first to jump into the opening over the platform and snag the armor. After this is done, tap the computer to de-activate the yellow laser beams in this level.
You are now done with this level. Proceed back to the prison cell, and to the Security Complex.
