Yeah. That's nice ideas.
Possibly if it's Possible:
-Rank weapons(More Rifle weapon, Machine Guns etc.)
-Killstreak rewards.
-Shops with special things.(Choose secondary weap there, MG42 for one min, Mine if anybody want to come in my base or Something) :]
That mine sounds like a very nice idea. We could defined use some shops or something to spend our money on. Hopefully more contribute ideas. With updates, base will hopefully grow and become more popular
