Hello I'll just keep this short I couldn't find any files on the mark v b undersuit from Halo Reach , so I decided to take the raw file from the in game pull , and I tweaked it up and made it simple but I started working on the abdomen and gave it a few more details , I will continue to work on the neck and elbows and thighs for you all , this should fit directly under your armor , but I imagine you wouldn't be able to move very well but if its accuracy and stance you're looking for this is for you , would love to see someone do a rubber type mold .
