Sure, they've got a couple four-eyed scientists, but one look at all the others tells you they're seasoned fighters. Oh, and dig this; They're not using guides.'|
Build 3120 features a presentation map called Generator. It is basically a cut-down version of the Generators map from the original S.T.A.L.K.E.R.: Shadow of Chernobyl, which was apparently intended to be used as an interactive intro. The map features Scar, as he leads a squad of ISG troopers (callsign Delta) down a large trench. In the background, the ISG members communicate with command, mentioning that they are in position. Then they are attacked by snorks, which are promptly defeated. Once they reach the generator, however, a blowout triggers and the team is wiped out, except for their guide, Scar, who is retrieved by members of Clear Sky and the game begins proper.
