Amazon Game Studios has revealed a surprise in-game currency with upcoming sports fighting title Breakaway.
During TwitchCon, an annual event celebrating video game streaming company Twitch, the Stream+ currency was briefly unveiled.
Ars Technica reports that the currency will "integrate directly" with Twitch as the retailer looks to chase monetisation with the sale of the coins.
Users can earn the coins by watching other streams, with the intention of using them to gamble on eSports heats.
Twitch was snapped up by Amazon in 2014 for $1bn – Breakaway as an Amazon Games Studio title will give the company a golden opportunity to test its new in-game currency.
It was not revealed whether users could trade or purchase the currency.
