Just kidding. This is Serious Sam we're talking about. They delayed with a joke and an explosion.
Though the release of this latest edition of Serous Sam was originally scheduled to appear on PC and Stadia in August, Croteam and Devolver Digital released this video this morning, effectively communicating that the game has been delayed to September 24:
The plot for the new game sounds like it will be more of the same (which isn't a bad thing): "Humanity is under siege as the full force of Mental’s horde spreads 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."
The PR statement from Croteam and Devolver Digital ensures fans that this new date is "100% not-gonna-change", so it looks like we can expect to see Sam by late next month.
