Have you tried out Rise of the Tomb Raider's Twitch chat integration?

Rise of the Tomb Raider is one of a small number of games that leverage Twitch integration to great effect.

Viewers can influence a Rise of the Tomb Raider Twitch stream by voting on challenge cards.

To activate this feature, a streamer needs to choose Expedition mode. At intervals, viewers will be prompted to choose between two Expedition cards, with various effects. The streamer must then endure the outcome for five minutes.

There are 64 different cards, and while some are straight up difficulty modifiers (in both directions), others have silly or cosmetic effects.

Those who watch and vote on a stream through the Xbox One Twitch app will receive in-game bonuses for their own Rise of the Tomb Raider play through, which is pretty sweet.

Visit this Twitch FAQ to learn more about the feature.

This isn't the first game to make use of Twitch in this way; indie horror game Daylight had similar features. (That game scared me so badly I unleashed a torrent of psychic hate that may or may not have been responsible for Zombie's subsequent closure.)
