The Forest has been made available on Steam for those willing to have early access to the Alpha version of the game. There are obviously quite a good number of bugs and glitches but it should give you an idea as to what to expect anyway. You play the role of a man whose plane has just crashed and whose kid (?) has been kidnapped by the locals. The odd thing is that before the crash, he and the child were the only passengers in the plane, which seems to indicate there's some kind of mystery going on. Once on the island, he will have to organize himself in order to survive the deadly conditions, which means feed himself, stay dry and avoid the locals at all costs.
Note: The frame drops you can see are due to the capture.
