Thanks Neco. The arms bursting through the walls is actually an iconic scene from Day of the Dead which I was nodding to at the end of the teaser. You'll notice I also managed to get the same calendar on the wall!
Well as is expected with my ignorance of old horror movies - Feels good to be proven wrong, hah. Well, the horror movie buffs out there probably really appreciate those details and touches, as a horror-game-buff though, I'll definitely look forward for more :)
