both would totally destroy the athmosphere of such a game, you won't feel hunted, scared by those monsters...
well... I don't think so (as long as it won't get too much like a shooter).
But It would definitely make It harder to get the gameplay rvL_eXile is looking for.
Multiplayer would be really interesting, but if you'll have weapons then just weak ones (f.e. melee) or with very limited ammunition and also not through the whole game, just at some special parts.
