Facebook co-founder creates assassin Twitter game at SxSW

Watch out for flying Nerf darts at the Austin Convention Center this weekend. There is a sub-culture of geeks in central Texas this weekend and they are packing heat. It's an interactive Twitter game at South by Southwest this year.

Andrew McCollum, a co-founder of Facebook, came up with the idea for Assassins. He even created a bot that manages the game. The iPhone interface for checking up on the game can be found at http://assn.startupdistrict.com/.

If you see someone you want to shoot, send a direct message like this: "d assn target @username" to confirm you target. Once you have shot and killed your target, quickly take a picture send a direct message to assn saying "d assn kill @username [twitPic link]".

If you fail to shoot your target, you have to say "d assn fail @username".

From the welcome emails: "The first rule of SXSW Assassins is that you do not talk about SXSW Assassins... unless you want to."

Tomorrow a new element of Assassins will enter into play: bounties. Let's say Gary Vaynerchuk is up on stage speaking. If you shoot him while he's talking, you might score bonus points.

Keep your eye on @assn on Twitter, or compeltely avoid it if you think it's non-sense.

Some people are going a little overboard, but it's all in good fun. I'm talking about Director of Product Strategy at Raptor, Kevin Cheng.
