Penumbra - Overture announced!

[Jusal]

As for the melee combat system I would suggest not making it very powerful. Mostly something like smacking an enemy with a crate from behind the corner to make it lose it's balance and then running like hell while it's still down. A good hit with something heavy would perhaps result in knocking it unconscious. Complete killing should be made pretty hard to do unless the creature is naturally fragile or something.

Just my opinion though.
