Serious Sam II 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. In multiplayer, up to sixteen players can play the campaign cooperatively or engage in deathmatch.
