personally, i'd rather the extra campaigns to be free :/ but yeah, great game :) i loved the weapons :) though i wish we could like port weapons between campaigns~ it would be awesome to use that weapon that has those floating homing rockets in the 1st campaign XP also, you should add an achievement for getting all the weapons to level 10 :o
you should add an option to send allies away to to disable perks like that one that send damage back because it makes doing the challenge in the first mission of that 2nd campaign rly hard (the one with the killing all enemies with only stolen guns)
