So Nyan Cat is in Unreal Tournament 3

A group of modders got together and replaced the area-clearing, uber weapon from Unreal Tournament 3, the Redeemer, with Nyan Cat. If you're not sure what Nyan Cat is, you can follow this link to the original video and bear witness to an internet meme that some find hilarious and others use as an excuse to never wander around on the internet again.

It's a PC only mod meaning that I might have to fire up UT3 just to try this out. Or to see who will have the guts to use this in multiplayer.
