Serious Sam HD: The First Encounter is an HD remaster of 2001 FPS Serious Sam: The First Encounter developed by Croteam.

The story takes place in a near future where humanity has unraveled an ancient artifact in Egypt which allowed for major technological advancements such as deep space travel. While exploring the space, Sam awakens an alien named Mental that destroys any intelligent life in the universe every 100.000 years. In an effort to save humanity, scientists send Sam back in time in order to kill Mental and prevent any destruction from happening in the first place.

The game features large-scale linear levels that are free for the player to explore as there are secrets hidden throughout them. Most of the levels follow a similar pattern of multiple arenas where players fight several waves of enemies connected by a pathway between them. The scoring system is also present. Player's score depends on the difficulty they play on and on the type of enemy they kill.

Players can get additional information on the enemies, weapons or the surroundings via NETRICSA, an implant inside Sam's skull.

Serious Sam HD: TFE also features multiplayer and co-op with up to 16 people.
