i think all we know at the moment is you can unlock weapons in the shop by finding their blue prints in single player, and then you buy it in the shop using cash from different game modes. They haven't said, but I would be surprised if things didn't unlock in the shop by leveling up as well. --- PSN: LawnGnome93, Playing: Civilization V I'm a Civ addict and there's only one remedy.

We have absolutely no idea if Rank has anything to do with the store where you buy weapons, suit upgrades, and suit parts.
The rank of old went up to Rank 25 (If i remember right...) and i'm guessing its even higher this time around. --- Sparkster returns after 16 years in..... "Rocket Knight" My Alias for Wii Online = "Shader" Monster Hunter Tri = "Deimos"
