Serious Sam 4 story trailer has launched, giving fans of the new first-person shooter installment something to anticipate as the game prepares to launch this week.

Here’s the summary about the game via press release:

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.

Croteam returns with a high-powered prequel to the Serious Sam series that scales up chaos to unprecedented levels. The classic Serious Sam formula is revamped by putting an unstoppable arsenal up against an unimaginable number of enemies that requires players to circle-strafe and backpedal-blast their way out of impossible situations.

Published by Devolver Digital and originally announced as Serious Sam 4: Planet Badass before it was dropped, Serious Sam 4 is a prequel to Serious Sam 3: BFE and was slated for release on  2019 before being delayed and retitled due to problems with localizing the subtitle with other languages. The game is scheduled to be released on September 24 for PC and Google Stadia, with PS4 and Xbox One releases to follow in 2021.
