Firstly, that video was quite an experience, I must admit. That dismemberment at the end... Reminded me the horrible deaths Isaac Clarke had in Dead Space series but with a little difference: The real horror is us. Seriously, the video released by Bethesda is extreme fun; you should check it out:
The new DOOM will be released in May 13th, and we will be waiting restively for unleashing hell on citizens of hell.
