Worms Armageddon.
That is all.

A short game, but definitely worth playing.
While it does have some tense moments when you are being chased by the creatures or are required to sneak around them in small rooms, over all it wasn't really all that scary, the storage area was pretty creepy, and it DID have fantastic atmosphere, but I was never really jumping out of my seat of trembling in my seat. It doesn't really help the actual creatures are really goofy-looking up-close though.
(And yes, I played it properly, 5.1 headset, fullscreen on a 5760x1080 display, all lights off, dead of night, etc.)

Still a fun and really interesting game though.

This game is awesome and it always will be.
But this version is a really old Windows 98 port that they've just repackaged and sold on Steam, so the resolution is terrible and there's no windowed mode, among other issues such as iffy controller support.

You'd be better off waiting for New & Tasty at this point.
