The Defiance site has been updated with the news that both the F2P PlayStation 3 and XBox 360 versions of the game will be delayed due to a persistent stability issue that has been plaguing servers all week. The F2P console versions of Defiance were due to be released today. The announcement concludes with the news that no ETA has yet been determined for the free to play console launch.
As you’ve seen or possibly experienced this week, we’ve been having stability issues with our console platforms. The team is working on a number of game additions as part of its crossover with Season 2 of the Defiance TV show and the latest build has negatively impacted game stability. Our programmers are working on addressing these issues.
