I'd have it set up so that there'd be backtracking and interlocking areas and everything. It'd be optional to do it over-the-shoulder or classic camera. If it's over-the-shoulder you gotta get shots right between the eyes for it to be a headshot =)
Love the camera style select option. There better be lots of recoil so you can't get trigger happy either. There gonna be multiple SINGLE player storys to play through. We both know coop in a horror game is unnecessary and a bastardisation and insult to the genre.
If this game wasn't gonna be sick; then I wouldn't be posting on this board, guy. Long story short.... THIS. GAME. IS. GONNA. BE. sick.
