I might actually turn my whole HUD off....
I will be. Unless there's no way I know that I might die, like something slowly draining my hp. I'm not sure the extent of the visual/sound queues.
I probably won't use the map either (wish they would have done a map like Far Cry 2, viewable in the player characters hand, but oh well), unless it's needed. If the compass can be used just for directions (every thing removed except N, S , E, W) then I'll just use that, and refer to the QL for general direction's. Hopefully it can be called on though. So it's not on the screen the whole time.
