Hmm, some of that information is new to me, and I thought I was planning this thing!! <G>
The official party announcement can be read here:
The band, Lucid, may or may not be there. Getting them to the field is something thats still being worked on, they are recording a new album right now and they may not have the time.
Its supposed to be a 1 vs. 1 Top Gun tournament with AGD Sydarms.
As for the mini-3man tournament, thats news to me.
You can pre-register by going to the store, like he said, or by sending Riotz a message on Automags.org.
Paintball2Extremes magazine may also be present at the event.
Go check out the official post, and then make sure you show up!
