E1M9: Central Processing (The Invasion)

E1M9: Central Processing is the ninth and secret map in episode The Rock of The Invasion. It was designed by Paul Fleschute (Moe).

Secrets

 * 1) In the blue key room, pick up the blue key, then press on the misaligned wall to the north. The switch here lowers a lift to the east, taking you back to the hub. (sector 119)
 * 2) In the northeast field, head down the steps to the nukage and before using the lift, head to the north wall and use it. Take the lift down afterwards, then press the switch at the southeast end to open the northeast corridor. Follow it to the next switch and there will be a path going south. There will be medikits (not on Hey, Not Too Rough or lower) at the bottom, and you can use the southwest corner as a lift. More medikits are to the south, and to the west you can press a switch to obtain rockets and a rocket launcher. (sector 163)
