I've been having a lot is f fun with Green Hell, which was on sale recently. It has a surprisingly good story for a survival game that gets better the further along the game.

There's one very annoying bug though. If you save, harvest something, die and reload, the resource does not respawn. This can really screw you over if you get an infection, you find and harvest some medicinal plant and then still die because it took you too long to find. Because when you reload, the plant you finally found is gone and now you need to find another, even further away!
