Hey there , I'm a metal gear solid fan as well and as much as I'm sure id love the skull suit I'm afraid theres 1% chance of getting one the reason
the actual suit has ammo compartments for snakes ammo
has slots for pistols
and etc
that would require 3-d modeling and i don't think anyone has comeout with a script for the models o be added or they just haven't attempted it.
I could do a version of it however , but it would be a basic grey suit with some drawn on boots and maybe some ammo box`s if i get the 3-d shading just right , but I'm not promising anything :/
p.s the bandanna will NEVER work , i don't think people have that kinda time these days.
