Interesting, but most of what they offer... I already have in ArmA2 (and the upcoming ArmA3)... if not better.
Anyway, I'll consider backing them.
I'm just disappointed that even with all this customization, the choice of camo is not for the player to make, but for the admin/mapcreator. Some people are just terribad at selecting suitable camo (black camo for example is next to useless... even at night).
