Serious Sam 4 is a first-person shooter developed by Croatian studio Croteam and published by Devolver Digital. It is part of the Serious Sam series and a prequel to Serious Sam 3: BFE. The game was announced in April 2018, originally as Serious Sam 4 Planet, and is set for release in September 2020 for Microsoft Windows and Stadia, as well as PlayStation 4 and Xbox One in 2021. Serious Sam 4 takes place in several locations this time around. So far the only confirmed locations are rural France, Greece, Italy, Mt. Vesuvius, Pompeii and Russia.

Taking place during the Mental War and prior to the events of Serious Sam 3, humanity is under siege as the full force of Mental’s hordes spread across the world, ravaging what remains of a broken and beaten civilization. The last remaining resistance to the invasion is the Earth Defense Force led by Sam “Serious” Stone and his heavily-armed squad of misfit commandos.

It is known so far that Serious Sam 4 will include nearly all of the enemies from Serious Sam 1. Most enemies from Serious Sam 3 are also making a return, along with a few enemies from Serious Sam VR: The Last Hope. It has also been confirmed that the game will offer some new variations of classic enemies, and that there will be over 30 different enemy types in the game.

Serious Sam is a video game series created and primarily developed by Croteam. It consists predominantly of first-person shooters. The series follows the advances of mercenary Sam "Serious" Stone against Mental, an extraterrestrial overlord who attempts to destroy humanity at various points in time. The first game, Serious Sam: The First Encounter, was released for Microsoft Windows in March 2001. Several spin-offs were developed by other developers, such as a Palm OS conversion of The First Encounter by InterActive Vision, Serious Sam: Next Encounter (on GameCube and PlayStation 2) by Climax Solent, and Serious Sam Advance (on Game Boy Advance) by Climax London. All three were published by Global Star Software.
