Walkthrough[edit]
Essentials[edit]
You only need the red key to finish this map. For the quick way, head into the hallway to the north. You can do this by pressing the switch on the area that you are on to open two garage doors, then climb the steps up heading westward through two doors. You can also climb the silver steps and take either northern door to reach the hall, then go westward through the door to appear in the large western hallway. Head through the door to the south and the door behind it. The red key will be in this room, so take it and run all the way back down the hallway to reach the "SIMU EXIT". Press the furthest panel on the right to exit.
Other points of interest[edit]
Secrets[edit]
- At the start of the level, enter the doors, and then head through the western door and up the stairs. You will hear a door opening in the northeast. Run into the core facility as quickly as you can, and run through the newly opened door to find a megasphere. (sector 146)
Bugs[edit]
A medium and hard difficulty imp (thing 221) is stuck inside stairs in the hallway room joining the walkways.
A body impaled on a stick (thing 227) placed between the dual walkways in the core room snaps up and starts hovering when the nearby door in the southeast (sector 19) is opened.
