obvs load more customisation...
But for me the masks and helmets really made the game for me on apperence i got addicted to making masked characters

Also maybe customisation on the guns like designs on the side, paint jobs such and such....
(This one's just cus id like to see it) 3rd person perspective? just cus i wanna see my character but if not them im fine just an idea.
Im a gore person soo more blood and maby limbs and various body parts flying occasionally.
Other two handed weapons like shotguns or snipers????
Maybe proper armour with bonus to health or extended health

These are just a few of the things i would like to see im not picking at the game cus i LOVE it just ideas floating in my head when i play it IM ADDICTED!!!

But comment or rate if u give a crap
THANKKYOUUUUUUU!!!
