On this eve of Christmas Eve, kristus and shaviro bring an exciting new project announcement: Doom 3: Phobos. Being created by your friendly neighbors of Team Future, this unofficial expansion is sure to be the greatest thing since sliced bread; either that, or Doom 3 itself.
Well, I'm not about to write a big old narrative about this thing, so here's some info copy and pasted from the site:
The portal was closed. Hell was defeated. Wasn't it? The stricken plains of Mars were only the beginning. Now, the second wave is coming, a hellish onslaught originating from the dimensional gateway hidden within the Martian moon of Phobos. Discover the extent of the UACs plans for teleportation technology, battle against impossible odds to escape the haunted Mars base, and race to reach the secret Phobos Labs, where science has infringed on the dimensional boundaries of the universe.
Phobos is an unofficial sequel for Doom3, following right where it left off. Featuring new enemies, locations, weapons and music, we aim to create a highly immersive and mystical journey throughout the Doom universe. Furthermore Phobos will feature what should really cater to the oldschool doomer's tastes while still staying true to the standards set by Doom3.
