Whoa, paintball in
the future!
This is something I've considered adding, but decided not to for a few reasons:
a) People would refuse to update because it would put them at a disadvantage.
b) If I made it optional, most people would probably just disable it, except for the new players that didn't know how and would be at more of a disadvantage than they already are.
c) You don't really "see" real masks while you're wearing them. They just reduce some of your peripheral vision, which you don't really have in the game to begin with.
I suppose it could be added as an optional feature, disabled by default...
