I don't normally go for horror rp's, but I'm trying to broaden my horizons and this looks like it could be fun - I already have an idea for a character who so doesn't want to be there because he knows how horror movies usually goes and he really doesn't want to die, but went anyway because one of the usual tech's got sick and called in a favour. 
Also don't be discouraged! Sometimes it takes a few days for an rp to get going, I'm sure more people will join soon!
