Those ARE some very nice models. I downloaded the flamethrower and grav hammer. I can unfold them too, but it would take me a while since I don't really have a knack for it yet. However, I don't have a password so I wouldn't be able to save the unfolds, BUT I do plan on getting it sometime since I have models for female builds that are not unfolded and I think it would be of some use to some of the females on the site that want to build stuff for themselves too!
If you could get me Kat's armor (halo reach) modeled for me, that would be AWESOME! I was thinking about making her stuff to wear for the release, but I still have NO CLUE how I would make her prosthetic arm! That part is really bugging me about her.
