Sooo...you have to pay to progress through the game? You can't reach tier 2 with your sniper bank unless you pay $5? Then you can't reach tier 3 unless you pay $10? I've looked through everything I can find and see no way to use what you earn to progress to higher levels. It looks like of you don't pay...you stay at the basic stuff at level 1, regardless of how well you do and how much you earn
