We are playing a custom gametype league, with a relaxed format.
Having previously played on Openwarfare with gametypes such as assassination, team greed, hide and seek, and at one point, paintball, we are currently enjoying freezetag. Maybe this is because of our Moh:AA roots!
With all match servers owned by the league, there is no maintenance and no map uploads for clans to worry about. The lack of a fixed match regime means matches can be played in a friendly manner around existing commitments.
