Striking Distance Studios has announced a DLC for The Callisto Protocol called “Final Transmission,” with the expansion set up to be the game’s “final chapter.” The Callisto Protocol DLC is slated for a June 27 release on PlayStation with other platforms to follow on June 29.

A trailer for Final Transmission was also uploaded via the game’s official Twitter account:

Given that the tweet mentions Final Transmission as The Callisto Protocol’s “heart-pounding final chapter,” it’s possible that this will be the one and only story DLC for the game. It’s also unclear whether or not we’re slated for any more story content following this, which may be a disappointment to those who enjoyed the game’s narrative elements.

The Callisto Protocol was released last December 2, 2022, with the game failing to meet sales expectations that would have eased the game’s massive $162 million budget. The game was also plagued with performance issues on release, which affected its initial reception among players.
