This mod basically changes the inventory screen sprites for troopers wearing Power/Flying Suits, following the later Terror from the Deep helm-under-arm style that preserves the individuality of each soldier.
Actually most of the graphic work is Bomb Bloke's, so big kudos to him. I just adapted the whole thing to OpenXcom and fixed some tiny pixel inconsistencies.
As usual, extract the .zip file to your OpenXcom's data folder and append
options.cfg accordingly. Enjoy!
