Well, Daikatana is definitely very different than Quake III and Unreal Tournament as they are multiplayer-only games and Daikatana is a single-player game with multiplayer included. As for single-player shooters, Daikatana is really different in the fact that you travel with two sidekick characters through four different time periods within a large story. It's not your typical, basic shooter or team-based/mission-based shooter either. It's mostly an action adventure.
