Doom 3: Resurrection of Evil

Resurrection of Evil arrived on the PC in April of 2005 and for Microsoft's Xbox in October of the same year. The expansion introduced a few new weapons and enemy types not present in the original Doom 3 but largely kept the gameplay of the original intact, however with a slightly larger emphasis on action. The new weapons consist of a double barreled shotgun and the Ionized Plasma Levitator (effectively a "grabber", similar to the gravity gun in Half Life 2).The only brand new gameplay addition in Doom 3: Resurrection of Evil is the use of an artifact called the Hellstone, which looks like a human heart. It gives the player a brief period of time to use a key set of powers. These powers include slow-motion, enhanced damage and invulnerability, and are gained by defeating bosses throughout the game. The Hellstone is charged using the souls of dead bodies which litter the levels.LevelsErebusMain ExcavationErebus Dig SiteErebus LabsErebus ControlErebus ResearchErebus StationPhobos LabsTeleportationMolecular ResearchMain ReactorTeleportationDelta LabsHellSystem RequirementsFull version of Doom 33D Hardware Accelerator Card Required - 100% DirectX 9.0b compatible 64MB Hardware Accelerated video card and the latest drivers.English version of Microsoft Windows 2000/XPPentium IV 1.5 GHz or Athlon XP 1500 processor or higher384 MB RAM8x Speed CD-ROM drive (1200KB/sec sustained transfer rate) and latest drivers2.2 GB of uncompressed free hard disk space (plus 400 MB for Windows swap file)100% DirectX 9.0b compatible 16-bit sound card and the latest drivers100% Windows compatible mouse, keyboard, and latest driversDirectX 9.0b (included)
