Warhammer 40,000 Online

David Adams: The fact that Warhammer 40,000 is science fiction and not fantasy goes a long way to distinguish the game from other Fantasy MMOs, such as Warhammer. Besides the obvious visual differences, the setting also affects many aspects of the gameplay.

First off, unlike a fantasy MMO, guns play a major role in the dynamic of combat. The gameplay will be much more intense, focusing a lot on fire-fights, tactics, cover and general brutality (which is befitting a game set in the grim future).
