MAP10: Bridge (Icarus: Alien Vanguard)

Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Essentials
This map is non-linear, and you just need to find the red key to exit. It is in the northern part of the map at the large bridge room behind the black wall. After you get it, head for the exit which is in the room south of the big computer room east of the bridge. If you are coming from the starting point, it is the first door on the right. The exit door is marked as "PLANET EXIT" and again, press the furthest panel on the right with the red key to leave the map.

Secrets

 * 1) In all of the rec rooms, there is a wall bearing blue lights.  Open any one of these to find a secret hallway leading to the bridge. (sector 147) On Ultra-Violence or higher, this will also contain two bulk cells.
 * 2) In the eastern computer room, press on the north or south sides of the mainframe at the very south, second from the east.  It will lower like an elevator.  Ride it up, and then jump across the other mainframes to the northwest closet, which contains a soul sphere (on Hurt Me Plenty or lower) and a plasma rifle (on Hurt Me Plenty or higher.) (sector 66)
 * 3) The northern wall of secret #2 has a different texture than the rest.  Open it to find a megasphere. (sector 193) Note that this will also open an alcove, letting out an army of monsters.  In this are two stimpacks and a box of ammo.
 * 4) Lower the aforementioned mainframe, as if you were going to obtain secret #2.  Instead, enter the green room, and run to the now exposed, inner corner of the table.  If you get there fast enough, it will take you up onto the table, where you can get a backpack and (on Hey, Not Too Rough or lower) two medikits. (sector 166)
 * 5) In this same room, a portion of the golden wall bears green lights.  Open it to find two medikits, two boxes of ammo, two boxes of shells, and  (on Hurt Me Plenty or higher) three bulk cells. (sector 170) On Hey, Not Too Rough or lower, there will be three medikits instead of two.

Routes and tricks
As with many other levels in Icarus that have "teleporter" or "begin simulation" exits, a death slide can be performed on this level in the exit hall. The rocket launcher on this level can be used to do so by blasting yourself off of the red computer panels with your back facing the teleporter, but the fastest way is to have monsters kill you. It's easier to do on Nightmare difficulty, where gunfire is constant, and you can run toward the exit as a bullet hits and kills you, sending your corpse under the exit. On Ultra-Violence or lower, however, the monsters are slower, so you will need to let the Cacodemon bite you to lower your health faster.
