I know i gonna get lots of brick for this, but when i was able to buy all the Vigors upgrades as well as all the upgrades for my shotgun and Sniper rifle (my two main weapons) and not buy anything from the dollar bill vending machine iam not sure that i play the right Mode, is not that hard like Ken Levine promise. I think the main reason for this is you trip over ammo, money, and medkits everywhere you go and the checkpoint doing too well. Maybe super 1999 mode for the next Patch Ken Levine ? (Patch not the the DLC 4A Games)
