The ability to move on walls and ceilings would look organically.

The horror of the abyss.

I lacked one thing in the game - the ability to summon birds. Now I play Postal 4 and there are pigeon mines, sorry Corvo can't do that - he caught up with the birds on the guards, they were distracted, and you ran past.
