Unit 7 - Level 4 - Inner Hangar

Objective: Locate hangar control, and close the main hangar bay door. 

U7L4W1

Collect the ammo pack, armor shards, and power shield while blowing away the Gunners. 

U7L4W2 (secret)

Right when you enter this level, look at one of the large computers to the left. There’s a crack in it and it’s sparkling so shoot at it to snag the adrenaline boost. 

U7L4W3

Descend down the stairs on the right side and dispose of the beserker and brains. On the hard level, three more beserkers will charge out of the wall. Grab the stimpacks in this room and shoot down the Icaruses.

U7L4W4

Next, enter the vault-like door to the turbine chamber and allow the turbine to blow you up. When up top, kill the Strogg and press the computer to de-activate the turbine fan. (note: you may have noticed you can also enter this chamber by climbing up the crates on the outside but the door can only be opened from the inside first. I do recommend going up there to grab the mega-health in the corner! Be forewarned there’s a beserker hiding in the wall!). 

U7L4W5

Once inside and the turbine is turned off, drop down below and collect the health in the small hallway. Follow it around with some Gunners protecting a button. Once they’re history, press the button to open up the floor. Hop onto the post overlooking the water churner, and then onto the dry ground to collect some goodies. When you’re ready hop into the water and let the device slowly turn you around until you can enter an open room. If you move too fast or too slow between the turbines, it’ll slightly damage you.

U7L4W6 (secret)

Kill all the Gunners and beserkers and shoot at the hexagonal box with the crack in it. There is a quad damage in there. Scour the room for collectibles and you’ll notice the platform behind the computer leads you back up to the beginning of the level again.

U7L4W7 (strategy)

Head down the hallway and kill all the beserkers and Icaruses in your way. When you get to the room with the moving blocks over the water, step on the one closest to you and then onto the next when it is beside you. You may have to run and jump. Hop off and press the green button on the ledge to extend the ladder. Then get back on box number two and jump onto the third. This will take you to the ledge with armor shards, rebreather, and another green button.

U7L4W8 (secret)

When the lift is lowered, don’t hop on there right away. Dive into the water right where you are and swim down to an opening. Eventually, you’ll find an area to come up for a breather with some power-ups and health. Use the rebreather for all of this if you need to.

U7L4W9 (strategy)

Swim back around to the ledge and climb the ladder. Then, time it so you can hop on to the lowered lift. Take the ride up and jump off and into the pipe with the health stimpacks. Drop down and peg off the Icarus from where you are.

U7L4W10

Ride the large turbines and if you fall off, swim to ledge or down deeper into a small underwater area with a green button. This will drop the bars and allow access back out to where the lift is.

U7L4W11

While you’re on the large turbines, jump onto the ledge with the computer and zing the Gunner. Pick up any ammo you need then hop back on for a spin. Now, drop to the lower one to get the power shield on the ledge and back onto the lowest turbine. Wait until it opens to a dry area and take on the Icaruses and beserkers here.

U7L4W12

Both hallways will take you to a large room with a flying drone. Take it down and jump onto the island to step on the button in the middle. This extends the bridge across to the other side (above your head).

U7L4W13 (secret)

Hop into the water and look directly under where you were standing. There is a small opening with an adrenaline in it.

U7L4W14

Jump back out and enter the green-glowing room. Pick up the stimpacks and combat armor and kill the Gunner to get to the green button on the wall.  A ladder will emerge out of the floor so take it back up so you can walk across the bridge.

U7L4W15

Walk across into the room, pick up the stimpacks, armor shards, and press the button to lower the platform. Hop in for a long ride up and a bout with a couple of Gunners. Pick up any ammo you may need, and hit the lever to close off the hangar bay door above you. Now proceed to the surface.

U7L4W16 (secret)

Exit the door to the right of the switch and kill the brains and Gunners. Collect the armor shards and health and shoot at the panel to the lower left of the doorway with the illuminated yellow lines. It will open up to uncover another secret - body armor. 
Step on the platform and push the button to ride it to the surface.
