Noticed this a few times on the Halo 3 mission “Crow’s Nest” - there is a female marine that spawns with the “radio” backpack, but if you look closely the forearms are completely pure white in colour and seem to be missing the textures / skin tone.
There is a second bug that seems to occur with this same marine, where if she appears with both the radio pack and the helmet with the gold/orange visor, the helmet cannot be shot off properly (instead of falling off and revealing the marine’s head underneath, the helmet will fall off to reveal another helmet undeneath! This second helmet cannot be shot off at all and will stay on the marine)
The marine appears at the point were you are in rescuing the marines in the Barracks and Stacker says “Everyone on your feet” and the marines get up and help you.
I have never noticed this happening on any other level in Halo 3 (but I have also never seen any female marines with radio packs that are alive* either, only one appears in the entire game) *dead female radio marines also appear on Crow’s nest as well, didnt notice any problems with their arms, but the helmet issue is on the corpses as well
Also to point out that the model for the sergeant models seems very pale on the MCC build of Halo 3, more-so than on the 360 version?
(MCC) H3:ODST Sgt models are not as pale as the MCC H3 ones either
