Evaluation

Null & Peta -Invasion of the Queen Bug- launched on January 31, 2020. Shortly after launch, on February 13, 2020, TOKYOTOON announced a major content update was in development. That update arrived on March 9, 2020, adding two new stages, new bosses, new story content, new CG illustrations, new weapon upgrade levels, two new difficulty modes, expanded collections, and new achievements. This was the second and final major content release for the game. All DLC (the Art Book and Soundtrack) shipped on January 31, 2020. No further updates, announcements, or developer communications have been made since March 9, 2020 — now over six years ago. There are no unreleased DLC items, no outstanding developer commitments, and no indication from TOKYOTOON of any additional planned content. The game appears to have launched as a compact, self-contained product that received one post-launch content update before development concluded.
