Serious Sam 3: BFE is a first-person shooter video game developed by Croatia-based indie development studio Croteam and published by Devolver Digital. It is part of the Serious Sam series and the prequel to the 2001 video game, Serious Sam. The game takes place in 22nd-century Egypt, during Mental's invasion on Earth, as implied in The First Encounter. The game features a 16-player online, as well as 4-player splitscreen co-op campaign mode. The game was first released for Microsoft Windows on 22 November 2011. The OS X support for the game followed shortly after and was released on 23 April 2012. The Linux version of the game started being worked on after a high number of requests, where the first Linux-related update was the porting of the game's dedicated server. The game itself, however, was released one day after Valve opened the beta branch for "Steam for Linux", namely 20 December 2012. Gameplay Like previous titles in the series, Serious Sam 3: BFE involves fighting against many hordes of enemies in wide-open environments. However Serious Sam 3 has more closed environments than its predecessors, particularly in the early levels. There are also a larger number of enemies that can attack the player from a distance. There are 13 weapons in total, five of which have a manual reload. The signature close-combat weapons from the first game, the knife and chainsaw, have been replaced with a sledgehammer with three modes of attack. In the style of old-fashioned first-person shooters, there is no regenerating health, instead, there are health and armor power-ups scattered throughout the levels that the player must pick up. Additionally, the levels are full of secret areas, where health, armor, ammo, and in some cases, weapons from later levels can be found, following the tradition of the previous games. Some weapons such as the Lasergun and the Sniper Rifle and their respective ammunition pickups are in fact secret-only and otherwise are not found in the levels normally. There are no puzzles, however, the player must find keys, pull levers and find environmental anomalies to progress. Classic enemies such as the Beheaded Kamikaze, Beheaded Rocketeer and Kleer Skeleton return in the game. New ones include the Khnum and Scrapjack (resembling the Hell Knight and Mancubus from Doom, respectively), as well as the cloned soldiers reminiscent of the Strogg from the Quake series. The Kamikaze has returned to his original design,
