D4 Enterprise began distribution of "EGG Console Agress PC-8801" on October 8, 2026, priced at 880 yen with tax included. The 1986 Riverhill Soft adventure game follows the protagonist's search for his missing father, Dr. Duma, and his pursuit of Jason Cannack, a former assistant appointed director of the City Library. It is the 118th EGG Console entry.
The release is the 118th entry in the EGG Console line, which D4 Enterprise has built around reissuing older Japanese computer software. Agress is a command selection adventure: players investigate locations and talk to characters to move the story forward. The protagonist travels with his robot partner Amaroid Marie, and their exchanges are one of the game's draws. A Gallery mode includes the original manual and package jacket. The story turns on Dr. Duma's disappearance five years earlier and on the Blue Crystal, a fragment of an unknown ruin embedded in his right arm.
