Penumbra Prequel made in Amnesia

[The Rock Worm]

And they were totally harmless you had to hit a dog 3 times to kill it.

You need 6 hits even on "easy".

Don't think I've ever tried it on easy. It's much more fun and challenging to try it on hard. Of course it makes the enemies that much harder to kill. Even a dynamite didn't kill an enemy dog in one shot.
