Keep the phone ringing

Payment happens in your normal browser, not in here. Tapping a tier opens it outside the game. That is deliberate: a browser inside a game window has no address bar and no padlock, and you should never type card details anywhere you cannot check where you are.

No gameplay advantage, anywhere. Donor tiers unlock cosmetics on your phone and nothing that touches a world — no items, no kits, no priority. A phone that costs money to win with is a phone nobody wants on their server.
