Serious Sam: The Second Encounter +

Serious Sam: The Second Encounter is a 2002 first-person shooter game developed by Croteam and published by Gathering of Developers. It is the successor to Serious Sam: The First Encounter and the second game in the Serious Sam series. Taking place immediately after The First Encounter, it follows the soldier Sam "Serious" Stone, whose spaceship crashes back to Earth on his way from ancient Egypt to Sirius, requiring him to seek the Holy Grail to continue his journey. 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. The gameplay builds on that of The First Encounter while adding additional weapons, more enemy types, and platforming elements, and additionally contains the Seriously Warped Deathmatch mod by A Few Screws Loose.
