Rainbow Six: Vegas

Tom Clancy's Rainbow Six: Vegas is the fifth game in the Rainbow Six series of video games. It changes the series with multiple new features, such as a new health system where the player regenerates health while not taking fire (it should be noted that the player may sometimes be killed instantly, without a chance to regenerate health; this usually happens from grenades, as well as taking close range fire from very powerful weapons, particularly to the head). The player's vision is greatly impaired while damaged, similar to the health system in Gears of War.

Tribes: Vengeance

Tribes: Vengeance is the third game in the Tribes series, and the first to have a significant singleplayer mode. It is a sci-fi shooter with diverse character classes, expansive landscapes which can be traveled by foot, jetpack, or vehicle, and bases and base facilities to defend and/or infiltrate. The plot takes place hundreds of years before the previous Tribes games, and shows the events that take place prior to them through the eyes of six different characters over two generations.

Doom II

Doom II is the second game in the series, and it uses the same engine as the original. It introduced new monsters, a new weapon, and 32 new levels. It is also playable in GZDoom, and most of the information of Doom applies here too.

Doom

DOOM needs no introduction. It is the grandfather of the FPS genre as we know it. The GZDoom engine is a port of the originally DOS-based game that allows for high-res OpenGL graphics, mouselook, some widescreen support, among other things. GZDoom - http://grafzahl.drdteam.org/

Wolfenstein: Enemy Territory

Wolfenstein: Enemy territory is an online FPS from Splash Damage. Originally created as an expansion pack for Return to Castle Wolfenstein, the project was abandoned in an incomplete state, but the multiplayer component was quite playable, so it was released as a freely downloadable standalone multiplayer game. Gameplay is objective-based and heavily reliant on teamplay.

Pariah

Pariah is a first-person shooter computer game developed by Digital Extremes, co-developers of the Unreal franchise. It was released on May 3, 2005 for Windows and Xbox. It uses a modified version of the Unreal engine and the Havok physics engine. A demo featuring the multiplayer portion of the game was released half a month before the game. Pariah received mixed reviews from critics.
