MAP03: Inter-Base is the third level of Eternal Doom and was designed by Dietmar Westerteicher. You start off in a glass corridor and enter an underground base.
You can get the rocket launcher and chaingun on this level. To find the exit, complete each of the skull key areas - red, blue and yellow - and then backtrack to the blue key area. The mysterious tiled wall that would not open before is now gone. Enter the large area revealed and activate the devil-face switch.
The previous level is MAP02: Tower of Hell (Eternal Doom)
The next level is MAP04: Nucleus (Eternal Doom)
