Find the fear. yes the game is creepy, but as a an fps it's serviceable at best.
that said the enemy a.i. does in fact shine, particularly at hgr difficulties. it won't be beating a russian at chess any time soon, but it certainly makes you think, which is what a.i. is sposed to do anyway.
is it worth picking up? yeah. just don't expect it to be better than really any high tier game out there, and u won't be dissapointed.
