The game will offer a hybrid business model, with both subscription and free-to-play options. Sub fees will be "low" and come with bonuses and store currency. If you opt for the free-to-play angle, you'll only have a certain number of lives per day. Spend all of your lives, and you'll either need to stop playing for the day, buy more, or play with the risk of facing permadeath. Free-to-play won't be restricted otherwise, but may contain ads on the loading screen.
