If you are good you can keep getting bullets by killing people and stealing their bullets.

If they charge $40, nobody is going to play the game.

Not a supporter of the app, but it's pretty obvious the pay for bullet business model is the correct decision. It's hardly much at all considering the potential entertainment value for those who play it. Consider how much you would have to pay for paintball.

It's strange, it seems like on every single topic, nobody on HN wants anybody else to make any money at all.
