If you're planning to watch some Rise of the Tomb Raider gameplay on Twitch, it looks like you're in for quite the experience. Twitch has teamed up with developer Crystal Dynamics to give Twitch viewers a chance to influence the gameplay of broadcasters that are streaming from the Xbox One.
Specifically, when a broadcaster is streaming Expedition Mode through Twitch on the Xbox One, viewers will be able to vote on various cards that can spice up the gameplay. From Twitch:
"If you're a broadcaster, select Expedition Mode to give viewers the ability to impact your game play through voting. At various points of the game, viewers can choose between one of two Expedition cards — the card with the most votes will be activated for five minutes. This can cause the game play to become more challenging, a little easier, or unpredictably wild!"
In addition, viewers will get a chance to win prizes just by watching streams through the Twitch Xbox One app. Each time the broadcaster you're watching completes an event, such as a side mission, challenge, or crypt, viewers will get a gift that is redeemable on the Rise of the Tomb Raider in-game marketplace. Twitch hasn't said what the gifts are, but it's a pretty cool idea nonetheless.
