centaurianmudpig has announced that his WC-style space sim Absolute Territory is now taking beta signups. More than just flying around in space, the testing here also involves creating your own missions via a neat custom interface. If you'd like to get in early and help positively influence a fellow Wing Commander fan's work, head over to the CIC Forums here.
Interested in joining the Closed Beta? Fill in this form and you will receive more information closer to the event taking place. The main purpose of the Beta will be to test the in-game level editor for creating your own custom missions.
