What are you talking about? This is a game mode, not an event.

Here is a link about the WW mode, i hope this helps some. But this is a room mode, just like GB/GB2/CV/BB/BLITZ this is not an event.

Also, the only thing you get in this mode, is more xp, but you do lose crew, and your saliors all must be level 100. So its not for everyone to play. I have not yet played this game, cause I think losing crew at a higher % is crazy, I could care less if you get more xp. But crew is more important then XP in my book.

On kaiser server it is hard to get this mode running!
