Let the Obsession begin. Again. This time, the entire forces of the netherworld have overrun Earth. To save her, you must descend into the stygian depths of Hell itself! Battle mightier, nastier, deadlier demons and monsters. Use more powerful weapons. Survive more mind-blowing explosions and more of the bloodiest, fiercest, most awesome blastfest ever! Play DOOM II solo, with two people over a modem, or with up to four players over a LAN (supporting IPX protocol). No matter which way you choose, get ready for adrenaline-pumping, action-packed excitement that's sure to give your heart a real workout.
This is ManaMech's very first mod made for Doom II back in 2004. It has been tinkered with since then. This mod was desinged for multi-player, but you can run it in single-player and battle the monsters that were placed in it. There are two bases on either end of the map to fight for.
