Cheats, commands, and such.

[Yuhaney]

Well, no cheats or commands, but some mods are available if you're interested:

Unlimited painkillers, dynamites, batteries, etc.
Pitch-Black mods for Overture and Black Plague. Which means, you cannot see ANYTHING without a light source.

Also, someone made a mod that you can use dynamites, pick-axe and hammer in Black Plague.
