5 missions later and nothing changed. I beat the game and was never offered any new weapons or armor with the exception of a warriors emerald aegis which was the same as the emerald aegis but one defense point higher. the shop just stopped improving on its stock and there was never anything in any level that was better than what i already had equipped.
also i played with 2 controllers to get the 'team work' achievement and gave the new warrior character some extra armor and an extra weapon i had and he was taking off the same amount of damage that my level 20 character was. yeah level 1 and level 20 character taking off the same amount of damage. what a load of crap. i still had fun playing the game tho. it was worth 10 bucks i.m.o.
