Bungie aims to fortify the popular but flagging Destiny 2 with an expanded free-to-play plan and universal cross-platform saving, the company announced today. It’s an interesting and player-friendly evolution of the “games as a service” model, and other companies should take note.

The base game, which is to say the original campaign and the first year of updates, will be available on PC, Xbox One, PlayStation 4, and Google Stadia. You can play as much as you want, and your progress will be synced to your account, so you can do some easy patrols on console and then switch to your PC’s mouse and keyboard for the more difficult raids.
