Overwatch League has twelve teams, each with their own logos and colors. Sports teams have uniforms that are unique to their team, with variations that are used for either home or away games. As such, Overwatch League has in-game uniforms that are designed for each esports team. Players will be able to purchase the in-game uniforms of their choice with special currency.
Overwatch League Commissioner Nate Nanzer revealed in a video details about how Overwatch League home-team uniforms will be made available in-game in early 2018. All 12 home skins for the teams will be added to Overwatch.
The Overwatch League skins can be purchased with special currency called League Tokens. Players will need to spend real-world currency in order to obtain League Tokens. This system is being used as a way to provide monetary support for the various regional teams.
Purchase the home skin of your favorite Overwatch League team, and some of that money will go to support them. In short, Blizzard found a way to share a portion of the home skin purchases with the teams that they are based on. The League Tokens can only be used to buy Overwatch League in-game content.
In the video, Overwatch League Commissioner Nate Nanzer announced that, for the first month after the League Token system is launched globally, Blizzard will provide players who log in to Overwatch on PC, Playstation IV, or Xbox One, with enough League Tokens to purchase their first Overwatch League skin.
