Vanguard: Saga of Heroes is a massively multiplayer online role
playing game that was released in 2007. The game was developed by
Sigil Games Online and co-published by Sony Online
Entertainment.
The game was not considered a financial success and shortly
after its release Sony Online Entertainment bought out Sigil Games
Online and released most of Sigil's employees, rehiring a small
handful of team members to maintain the game.
Vanguard: Saga of Heroes can still be played and is now fully
owned and maintained by Sony Online Entertainment.
