Multiplayer In Crysis
Can't get Crysis multiplayer to work? Crytek know your woes.
For everyone struggling to get multiplayer to work properly, Crytek are on it. And while the connectivity issues are being hit with a thousand spanners, the company offers some helpful workarounds for those affected.
"Word from Crytek: We just would like to let you know that we are aware of the currently occurring issues regarding playing Crysis Multiplayer online. We are already in touch with Gamespy, EA and the world-wide server provider to resolve the problems. This topic has the highest priority for us now and we hope to come up with a solution as quickly as possible."
It appears problems lie when someone uninstalls their copy of the multiplayer beta, or the single player demo, after installing the full version of Crysis - something that's not uncommon after the massive promotional push to encourage interested players to have had a go at both before the full release. It appears to be killing the CD-Key, and the workarounds listed here should get you out of that fix.
However, this won't fix everything, and for those who aren't able to MP without CD key or Punkbuster troubles, Crytek can only ask for patience. But it's good to know they're working on it.
