Twitch users who watch Rise of the Tomb Raider streams will be able to interact with the broadcaster’s gameplay experience.
Expedition Mode will allow viewers to vote between two random modifiers out of a choice of 64, with the next five minutes of gameplay either harder or easier thanks to what they voted for.
In return, viewers can receive rewards such as access to new side missions, challenges, Challenge Tombs, Crypts and even some achievements.
The only catch for this to work is that broadcasters are using the Xbox One Twitch app to stream.
It might sound like a bit of a troll fest and truth be told, it could be.
