What hud options are there in this version of FEAR? Can you disable the hud?

I bought the game.

There are no hud options. You can't natively disable the hud.

However, there is a Devmode mod that will let you do it for Fear .

You can get it here:

It only works for Fear, not the expansions.

Can you figure out how to make it work with Extraction Point and Perseus Mandate?

No Hud mod for Fear and expansions here:
