planet. The different groups of NPCs help the player throughout the different settings of the game, with each group of NPC corresponding to a different setting in the game. Multiplayer A prominent feature in the previous Serious Sam games was cooperative gameplay, in which multiple players could play the single-player campaign together. Serious Sam 2 focused on this game mode even more than its predecessors, as it was the only multiplayer mode to be included when the game was released, although deathmatch was later added in a patch. The PC version allows up to sixteen people to play together, while the Xbox version allows four players, either via Xbox systemlink or Xbox Live.
