It looks like Croteam’s acclaimed fast-paced fps, Serious Sam games are coming to PS4 and Xbox One. The Entertainment Software Rating Board has rated Serious Sam Collection for PlayStation 4 and Xbox One. That is as good of a confirmation as any.
Judging by the last generation release, this unannounced collection might include Serious Sam HD: The First Encounter, Serious Sam HD: The Second Encounter, Serious Sam 3: BFE, and Serious Sam: Double D XXL.
Here is the ESRB’s description of the collection:
This is a collection of first-person shooters in which players battle aliens and monsters in frenetic combat. Players use pistols, machine guns, shotguns, and sledgehammers to kill numerous creatures. Large blood-splatter effects occur during combat. Enemies are sometimes shown blowing themselves up into bursts of limbs and blood. Players are also able to rip the eyes out of creatures’ heads and/or rip the hearts out of soldier-like aliens. During the course of the game, harpy-like enemies are depicted topless (though usually from a distance). One character briefly references drugs in the dialogue (e.g., “I’m supposed to be doin’ blow off a stripper’s a*s right now.”). The words “f**k” and “sh*t” appear in dialogue.
