FaraiweThe original Ghost Recon series, namely Island Thunder (I think earlier ones didn't have it?) had reward perks, for achieving certain objectives or completing certain missions.
One of them was MEGANOGGING, a setting in which the heads of the characters would be HUGE, easily half of the size of their bodies, which made sneaking around pretty impossible.
Can't find my screenshots or online images, too bad.
This is a memory brought up by NO REASON WHATSOEVER....
