Croteam and Devolver Digital have announced that a new DLC expansion for Serious Sam 3: BFE will be released for the PC this October. The "Jewel of the Nile" DLC will add three new campaign missions to the game which will task Sam with tracking down an ancient artifact and blowing up some aliens...so you know, another normal day for Sam. The content takes place in the middle of the regular campaign and will heavily feature two secret weapons from the main game: the sniper rifle and laser gun.

More aliens, guns and explosions? Sounds like Serious Sam to me.
