I doubt anything will hit the almighty viral heights of Twitch Plays Pokemon, but gosh darn if those crazy streaming kids aren't trying. Currently on Twitch: people playing through the original Halo as a mass collective. Incredibly, they've already beat the first level.
In case you don't know the deal, here's how it works: people watching the stream enter different commands as comments. People watching can comment 'W', for example, and that moves the players forward. The game responds to these multiple commands and there you have it: Twitch is playing Halo. Watch live video from TwitchPlaysHalos on www.twitch.tv It's kinda amazing that they've actually gotten this far. I'm actually properly amazed. Halo is hard and it's played in a three-dimensional space, I can't even comprehend how it's possible.
But things are getting a bit tricky. They're at the start of the second level and there's a fairly thin bridge that needs crossing. I suspect that's gonna be a fairly severe obstacle for the hivemind.
I honestly don't know if finishing this game will be possible using this system. How will they do the final drive/escape at the end of the last mission? It's gonna be tricky.
