Quantum Rush Champions

Quantum Rush Champions launched out of Early Access on December 4, 2014, arriving as a fully-featured product with 14 race tracks, 21 racers, 3 campaigns, and multiple game modes. Both DLC items — the Jumpstart Tournament campaign pack and the official soundtrack — shipped on or before launch day and nothing in the DLC list remains unreleased. Post-launch, the developer delivered several feature and balancing patches through May 2015, adding new Tier 7 boss characters, Steam Achievements, track optimisations, and gameplay balancing. The most recent news post directly referencing Quantum Rush Champions is the track optimisation update on May 21, 2015. After that date, the developer's news activity shifted entirely to their other titles — A.I. Invasion (October 1, 2015) and A.I. Space Corps (February 5, 2016) — with no further updates, announcements, or roadmap posts for Quantum Rush Champions. No future content was ever announced after launch, no unreleased DLC exists on the store, and the developer has not published any communication about Quantum Rush Champions since May 21, 2015. The store description presents the game as a complete, self-contained package. This is consistent with a game that shipped as a finished product and received a short post-launch maintenance window before the studio moved on to new projects. The completion date is set to the date of the developer's last other-game announcement (February 5, 2016), reflecting when it became clear the studio's attention had fully moved on, though the game itself had effectively been content-complete since mid-2015.
