i say a set amout of invisiblity per level like 1 min or something and every heat it resets like in a super hero mod kinda withought the weapon chang

this is a pretty cool idea i think ill expand on it

-mabee it could be like 2 creds
-you would get half transparant
-it would last entire round
-every round you use it you would lose 1 ammo
-mabee 10 ammo

also
-or mabee this could be in the armor catagory as invisibility
