Starting on November 15th 2012, XWIS (the official online service for classic C&C games) is inviting all players to "invade" the XWIS servers and play in what is being billed "MID MONTH YURI MADNESS" and there are prizes to be won!

Here's the blurb:
YURI MADNESS is a chance to reunite with some of your C&C buddies online, and play some 3 vs 3’s, or 2 vs 2’s (for fun) and WIN PRIZES JUST FOR PLAYING AND TAKING PART! The fun starts soon but in the meantime, dust off your CD’s, reinstall the game, get practising, get your clans organised and tell all of your buddies!
