The image comes from the first trailer for Dead Space 2, apparently called "Dementia" according to Scrambled Pixel, who somehow tracked the video down early. We say "early" since we're assuming this was the treat intended to be released tomorrow, on 4/29/10, the date coded into the Rorschach inkblot we received earlier this week. Oh, also because it's now been pulled from YouTube "due to a copyright claim by EA."
Don't worry though, we remember everything! It had the usual Dead Space fare: Necromorphs, Necromorphs vomiting, the Marker, crazy alien runes, and the above reveal (but not really!) of happy-go-lucky space miner Isaac's face. On second thought, you should probably just stop back tomorrow.
