Yah actually on second glance they are different games. Hmm.. wonder which one got the award I think it was the Wii one!

actually quake was on n64 as well.

I'm pretty sure the video was taken from the 360 version.

Either way I find it funny Left 4 Dead wasn't listed. That game has tons of blood. It flys in the air, splatters everywhere (including the screen), and zombies explode into a fog of blood. I guess they felt a few red pixels found in Quake was more deserving.

When I read the OP it also came into my mind, that Onechanbara was released on Wii and X360. But after seeing the video they mentioned only the Wii title which is

Onechanbara: Bikini Zombie Slayers

and not the X360 title which is

Onechanbara: Bikini Samurai Squad

Besides I played the Wii Version and I would say the scenes are from the Wii Version. (But I never played the 360 Version so I can't be 100 percent sure ...)

Also where is Sword of the Berserk for the Dreamcast?

I dunno gues they had a small list and had to include all the ones that had profound shock value during their heyday!
