SCATTERKNIFE is holding another tournament this saturday, it's 2v2 elimination but you can sign up as a solo player and you'll get matched with someone else. Details here: http://www.reddit.com/r/discododgeball/comments/28dgwc/saturday_showdown_sign_up/
Also, I've been very busy working on the next major update to Disco Dodgeball. It'll have a brand new game mode (Capture The Cube), more stats and achievements, as well as a huge improvement to the AI so it plays with more teamwork and also more fairly (e.g. it won't be able to collect and shoot 3 dodgeballs in extremely rapid succession). More details soon!
