The player is one of the mercenaries sent into the Zone. Officially he is to test the radiation levels around and inside the Plant. Unofficially he is to test the latest in the illegally modified combat technology. Since he is the first who may make it alive through the Plant interiors, his mission has been handsomely paid for by the Death TV - and they hope for a good show, paying extra for every kill - the more gruesome, the higher the bid. The game contains a very helpful and workable HUD with several cool features - energy shield, enemy detection, night vision and time slow-down. It also features 2 different gameplay models. Not different by mechanics (this is similar), but much different in how the player perceives it. Fighting outside, the combat is dense and fast - against many opponents. Inside the Dome it is dark, creepy, with horror sounds and stenchy atmosphere.
