MAP08: Phobos Anomaly is the eighth level of most console versions of Doom, based on the original E1M8: Phobos Anomaly with modifications made to adapt to consoles' limitations. The author of the conversion is American McGee, and the original authors of the map are Tom Hall and Sandy Petersen. The map first appeared in Atari Jaguar version, and is additionally used in the 3DO, Sega 32X, Game Boy Advance, Sony PlayStation, and Sega Saturn versions.

The map features two barons of Hell as bosses. A major difference from its PC version is that, rather than ending with the apparent death of the protagonist and serving as the end of the episode, play continues normally into the next level via a corrupted teleporter exit.

Comparison of versions[edit]

As well as geometry simplification, the following changes were made to the console versions of this level:

  • The slime pit at the start of the level is replaced with a raised platform, and the demons are replaced with zombiemen and shotgun guys. The lift leading to the pickups in the east chamber has also been removed.
  • The supercharge powerup behind the hidden door at the southern staircase is replaced with megaarmor.
  • After the barons are defeated, only the walls at the north point of the star will lower.
  • The open area beyond the star has been significantly reduced in size and made rectangular.
  • The exit teleporter and the staircase leading to it have been placed in an enclosed room. The teleporter also takes the player straight to MAP09: Deimos Anomaly with their inventory intact, rather than an inescapable ambush.
