We are officially up to 25 teams now including two pre-rookie teams from the St. Louis area. We would definitely still like some more teams to sign up though, there's plenty of room for more teams at the venue -

We are also planning to live stream the event this year with a much better setup - one GoPro for the main field view and two HD webcams for 1/2 field views that can be switched on the fly. All matches will be recorded and uploaded after the event.
Event rule changes will be posted soon. It will be similar to some of the others we've seen to limit can wars and provide an extra can or two to each alliance to maximize scoring.
