CyberStep will hold a collaboration event from 29 October 2026 featuring TERAVIT, a sandbox game built by its players, and BIG Dipper, an amusement facility operated by メビウス. The collaboration will include the Creators Grand Prix game creation contest, themed around BIG Dipper, which is now accepting submissions. The top prize is a set of BIG-kun and Dipper-chan plush toys and 10,000 Jewels. A Chat World and mini-games will also be made available as collaboration worlds.
In Chat World, the featured mascots BIG-kun and Dipper-chan welcome visitors, and a recreation of the Tachinomi-dokoro Heso venue also appears. Correct answers in the quiz-style mini-game earn rewards including limited skin parts and bingo-style items. A mini-game world called Lucky Battle Arena will also be launched, with the course of battles changing according to the displayed symbols. Players ranking near the top will receive limited skin effects.
The event period includes the mini-game and ranking events running from after the update through 15:00 on 19 November 2026, the collaboration Chat World launching on the same day, and gameplay elements in Lucky Battle Arena. TERAVIT is a free-to-play sandbox game that supports multiplayer and is available on Windows, smartphones, Nintendo Switch, PS4/PS5 and other platforms.
