Serious Sam: The First Encounter

Serious Sam: The First Encounter is a 2001 first-person shooter game developed by Croteam and published by Gathering of Developers. It is the first in the Serious Sam series. The game follows the soldier Sam "Serious" Stone, who is sent back in time to ancient Egypt in 1378 BCE to uncover information about the technologically advanced civilisation of the Sirians that could help humanity survive the attacks of extraterrestrial forces in the 22nd century. As Sam, the player traverses linear levels, either enclosed or set on open plains, and battles increasingly large waves of enemies with an expanding arsenal. During gameplay, the player can pick up new weapons and replenishment for ammunition and health, as well as review strategic information. In multiplayer, the game has two deathmatch modes and cooperative play for the single-player campaign.
