With Overwatch's closed beta relaunching today, Blizzard has revealed details of the online "hero shooter's" character progression system.
Levelling will work on a per-player basis rather than per-hero, with each level unlocking a Loot Box containing randomised items.
Loot boxes will only include cosmetic items, like skins, emotes, icons, and poses; Blizzard assures players "they won't provide any additional player power."
There will be no level cap in Overwatch, with dozens of items available for each character, and players will be able to exchange loot drops for in-game currency to buy specific items.
Blizzard will sell loot boxes in the future, but has not outlined the details of its microtransaction system.
Overwatch is due by the end of June 2016, for new-gen consoles and PC.
