About this guide

This guide tracks Mobile Suit Gundam Battle Operation 3 from public pages only: the Steam store entry (app 2303000), the Bandai Namco site, and the Japanese closed-test recruitment page. It is not affiliated with Bandai Namco Entertainment, Bandai Namco Forge Digitals, or Sunrise.

Pages describe the announcement as it stood on 29 Oct 2026. The game is not out. When a date, a price list, or a suit table shows up on those sources, the matching page here gets rewritten and the footer date moves.

A number lands on a page only if it is on one of those sources. Suit costs, weapon figures, and a launch series list printed by a news site are not here, because the studio pages checked on 29 Oct 2026 do not carry them. The closed-test roster is here because the recruitment page names those ten suits.

Screenshots are Steam store stills and frames from the Steam trailer, used so you can see the battlefield. They are not a claim of ownership.
