Rift horror Game Idea

Hey, i have a new idea of gameplay with rift.

This would be an horror game.

I had this idea while looking some Tv show suspense/horror, where often someone is in the woods,
there is a noise, he turn back and see nothing, just a branch moving.. like if someone has touched it, but no one is here.
And where ppl always die when not looking, or when being alone.. and we never see what the "monster" look like.


So the main Idea would be a game where we are in the woods or somewhere dark, we have to go somewhere and accomplish so stuff, enigma or bring materials to escape from an island or to send a SOS.
And "something" is chasing us.
It would follow us, making noise, and sometime attacking/killing us if we're not looking.
We would never know what it would look like , we would just see clues about its presence.

The only defense we could have would be to "look" in its direction, it would make it disappear momentaly (even if it never "appear" visually)..

So it would be some paranoiac gameplay, forcing us to look over our shoulder at every noise, to be sure we're not attacked. while being obligated to find our way, and resolve some enigma, so we should also look forward.

This would really use the "motion tracking" aspect of the rift.
We could also think of a multiplayer gameplay, where the menace is even bigger, but where we could look and cover each other with our vision, the best we can, while moving accross the place, trying to escape.

we could also mix things with sometmes savage animals, that would attack us even if we look at them, and where the only solution would be to run...
So run... or turn back to check the "ghost".. and move slowly... a really stressing game.
