Make the game scary/innovate
You make these trailers and make the killers seem like dangers but then turn them into pussycats, a lot of the maps are boring why can't we have a map set in some neon wonderland like vegas?
This game it just doesn't feel like a horror game to me. You could make a infection mode similar to what timesplitters 2 had but in this one you could have one really large map, 15 players, 1 player gets chosen at random to be the hunter and can infect survivors turning them into hunters. There is a timer, extra time awarded for each survivor infected and bloodpoints based on time alive and stuff. No rank, nothing like that simply a casual mode.
