I just don't have the credits to submit for a trainer for this game, but I certainly hope there is one released soon-ish. I haven't made it very far in yet -- but I'm pretty well scared !@#$-less.
It's not much a trainer could do, it's pretty much just the same as amnesia, just no inventory, healthbar, sanitybar or even a flashlight that needs battery.
Well I have to say the same. Does not seem to have anything that could be trained to help or give advantage. So unless you go through the game and find something that needs the trainer then. Not really worth time in my view.
