The chunky gameplay demo from the upcoming Doom was ultra violent, which has offended some. Bethesda's Pete Hines has responded to those criticisms during an interview with Polygon.
Hines emphasises the OTT gore is in keeping with the original Doom ("it's a game that definitely embraces over the top violence and tries to do it in a way that's fun...You're doing it to demons. If you were doing it to human beings in a very realistic setting you'd have a very different take"), but suggested, simply, if you're not happy with the level of the violence, don't pick it up.
"If you're not into violent, bloody games... Doom's probably not a game for you."
