Evaluation
Operation Abyss: New Tokyo Legacy launched on March 27, 2017. Its only DLC — a Digital Soundtrack and a Digital Art Book — were both released on launch day, functioning as bundled extras rather than post-launch content expansions. Developer communications consist entirely of bug fix patches from the weeks immediately following launch (the last post was on April 14, 2017), with no announcements of expansions, additional story content, or future updates of any kind. No roadmap, season pass, or unshipped content has ever been listed. The game launched as a complete, self-contained package and has received no content additions beyond day-one extras. There is no indication from the developer of any planned future content.

About this game
Two girls are key players in the incident...What do they know!?
Multiple reports of kidnapping have shaken Tokyo to its core. Regrettably, these reports are not baseless rumors...
The victims are mainly young people and their numbers have been steadily rising. Variants and members of a mysterious group have been sighted at the scene of the kidnappings. Students from Hinowa Academy—the very school attended by members of the Xth Squad—are in danger.
In pursuit of the truth, closely held secrets will be exposed...
But this is far from the only incident plaguing the city.
There are reports of strange incidents known as Sprawl Terrors, in which buildings and people suddenly vanish into thin air. A powerful enemy with mysterious origins opposes your efforts to investigate this phenomena. Furthermore, there appear to be some familiar faces among your enemies.
As the situation grows more desperate, loyalties will be questioned!
