The Xsyon development team has let us know that the full retail release of the game will be slightly delayed from March 1, 2011 to March 15th. Devs indicated that the head start program for those who preordered brought several previously unseen issues to the forefront and the team needed more time to address them. Players preordering Xsyon will have two weeks of free game time added to their accounts.
Reason: Since the soft launch yesterday (18th) for the pre-orders, we have stumbled across a lot of problems with our servers and bandwidth etc. We have now taken steps in order to get this resolved, and have now got brand new servers set up within the next few days. We have also given pre-ordered players an extra 2 weeks of playtime for free.
