In a release update video, Julian Gollop (Creative Director of Phoenix Point and CEO of Snapshot Games) announced the developer is delaying the release of the strategy game by three months with the new release being set for September of this year.
He explains that even though the game is "on track to be content complete much sooner", the delay will give the team the chance to "test and polish the gameplay much more extensively", making for a better end result. Gollop also added the decision was not taken lightly but will help the game live up to its expectations.
The fourth backer release is set for March, adding new content and details are to be coming up shortly.
