XLGAMES has announced that the server slam test for its in-house Studio Cube project, THE CUBE, SAVE US, begins on February 20.

This public test utilizes a build closely resembling the final launch version. The primary objectives are to verify server stability, test core systems, and identify major bugs. While some content is restricted, the test provides an environment similar to the official service to perform a final check on the game's quality. The test will run for approximately 72 hours, from February 20 until 10:00 AM KST on February 23.

The test build includes new content previously teased in developer notes. A new boss, Mutant Yacha, has been added, set against the backdrop of a temple map, along with new regular and elite mutants. A system has also been implemented where players can obtain exclusive gear by defeating elite and boss mutants. Additionally, the anti-cheat system has been strengthened to ensure a fair play environment. Players can also experience UI/UX improvements, general optimizations, and new cosmetic content, all of which reflect feedback gathered from global users during the Steam Next Fest.

THE CUBE, SAVE US previously drew significant attention during the Steam Next Fest, ranking 3rd in peak concurrent players and 8th on the global popular demos list. XLGAMES launched its official website on February 11, providing player guides, media kits, and the latest development news to strengthen communication with global users. The studio plans to actively incorporate feedback from this server slam test to enhance the game's quality ahead of its Early Access release.

XLGAMES is targeting a Q1 2026 release for the Steam Early Access version of THE CUBE, SAVE US. This server slam test serves as a final check for service stability and gameplay quality. Further details regarding the server slam test and Early Access can be found on the Steam page.
