This was revealed by the ESRB who recently rated for the game and according to the description, “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.”
We’re not sure if this particular collection will contain the same games as the previous collection, so we’ll just have to wait and see.
