Overwatch has rapidly become one of the most popular games on the market, and Twitch is looking to capitalize on the game's rampant fandom by offering up exclusive Overwatch League Tokens. The new promotion rewards viewers with in-game currency simply for watching the competitions in the professional Overwatch League — something that many fans would likely be doing anyway.
Tokens are coveted in Overwatch, as they allow players to purchase skins (i.e. weapon and armor designs). With the Overwatch League Tokens in particularly, players will gain access to special league skins that are only available to those who've watched the pros; no amount of money can purchase those tokens through the online store. Earning the tokens is just a matter of watching the pros complete live maps, with the promotion adding up to an average of 3-4 tokens per hour.
