Serious Sam 2

Serious Sam II (also marketed as Serious Sam 2) is a 2005 first-person shooter game developed by Croteam and published by 2K Games. It is the third main entry in the Serious Sam series, after Serious Sam: The First Encounter (2001) and Serious Sam: The Second Encounter (2002). The game follows Sam "Serious" Stone as he seeks to assemble the five-piece Medallion of Power, the only tool able to weaken his nemesis, the alien overlord Mental, who has each piece guarded by his forces. As Sam, the player traverses forty-two levels across seven thematic worlds and fights increasingly large waves of enemies with an expanding arsenal, vehicles, and turrets.
