I looked at the new team weapon skins today and noticed that the markza skin is green (also the LED is green for every skin except team ice, metal and rock)
Im hoping that this means in a future update we are allowed to choose from red, green or blue team skins for PvE, and potentially between green and blue for COG in versus.
It’d be cool if it stayed green in FFA, since there are no teams.
But I think it depends on the played character’s faction rather than the customization menu defaults.
