Atlus announced that The Caligula Effect's European release as a digital title on the PlayStation Vita has been delayed to an unannounced date. The game released in North America on May 5.

The Caligula Effect was originally delayed from May 5 to May 9 in Europe, but now it seems the game won't be seen on the European PSN tomorrow. Publisher Atlus has not provided a statement on why the game has been delayed, but they have stated they will announce a new release date in the future.

DualShockers reviewed The Caligula Effect and praised it for its ambitious systems and story, but lacked execution.

[Update]

Evidently, the delay didn't last long because the game is now available in Europe via PlayStation Vita's PSN.
