Serious Sam Classics: Revolution Serious Sam Classics: Revolution is a unified version of the Croteam's original Serious Sam Classic: The First Encounter and Serious Sam Classic: The Second Encounter experiences. The game started to be redesigned by Alligator Pit, an indie development team made of Serious Sam fans with support from Croteam, but it was “on ice” for a while due to life happening to Alligator Pit team, so recently Croteam took over the EA development and made it to the finish line. On top of everything available in Serious Sam Classics, Serious Sam Classics: Revolution includes additional enemies and 8 brand new campaign maps, including an epic new boss you can scrap with. Revolution is powered by an updated Serious Engine 1 featuring all-new advanced graphics shader support, full 64-bit compatibility, and Steamworks integration.
