Wondering why the Tyrian logo looks so strange? It reads "Tyrian" from upside down, too...
In the ordering information screens for LineWars 2, Safari Software was showing Tyrian as their upcoming game. The reason why it was released under Epic Megagames instead was because Epic bought out Safari Software before Tyrian's release.
There has been a major revision of Tyrian (2.0) that all users should upgrade to if they haven't already. Some major bugs have been fixed.
