E1M8: Launch Bay (Double Impact)

E1M8: Launch Bay is the eighth and final map of Double Impact. It was designed by Matt Cibulas (RottKing) and Ralph Vickers (Ralphis), and uses the music track "". The par time defined in the DMAPINFO lump of the edition released as official add-on is 5:15.

Secrets

 * 1) In the watery area northeast of the main arena, you will find a switch which opens the wall behind you as well as lowers the switch itself. There is also a switch on the backside of this particular switch, which you can still press even if you lowered the switch. The backside switch opens up two compartments, one with a medikit and another with a box of rockets. Both count as one secret. (sector 56)
 * 2) In the main arena, go to the northeast corner and drop into the nukage pit at the southern end of this corner (not the other nukage pit, there is no way to escape from that one). Press on the poison sign here to open the way to a lift, which takes you up to a plasma gun. (sector 207)
 * 3) At the teleporter north of the starting point, you can open the wall with slime on it for a health bonus. (sector 312)
 * 4) Open the next wall in Secret #3 for an armor bonus. (sector 316)
 * 5) Open the next wall in Secret #4, which is to the north, and you will see a dead zombieman. (sector 318)
 * 6) Open the next wall in Secret #5, which is to the east, and an imp will attack you. (sector 320)

Bugs

 * The progression of this map basically relies on activating four switches to access the southern area, whilst dodging three or four relentless cyberdemons. Each one of these switches will actually enable a crusher ceiling to kill a helpless and defenseless baron of Hell placed outside the playable area (there are no barons inside the playable area). Shortly after the last switch is pressed (they can be pressed in any order), the last baron of Hell will be killed and the tag 666 will be executed in order to lower the walls of the southern area.


 * Unfortunately, there is a small chance that pressing all four switches does nothing at all if the last baron of Hell happens to get entirely crushed before its death animation could end properly, resulting in a softlock. The version offered as an official add-on is not affected by this potential bug, since it does not rely on crushing barons of Hell to execute the tag 666.
