Serious Sam 4 Trailer

Devolver showed off Serious Sam 4 in today's presentation, confirming that Croteam's first-person shooter prequel is still on track for its previously announced August release on Steam. Here's word that comes along with the game's new Gameplay Trailer:
Humanity is under siege as the full force of Mental’s hordes 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.
