A new Mobile Suit Gundam Battle Operation title may be in development, as a SteamDB listing for MOBILE SUITS GUNDAM BATTLE OPERATION 3 Network Test has surfaced.
The listing, identified as Steam App ID 4946920, was first spotted on SteamDB on July 9, 2026, under the name MOBILE SUITS GUNDAM BATTLE OPERATION 3 Network Test. The listing received another record update on September 29, 2026, indicating that the app is still receiving changes in Steam's backend.
SteamDB currently has only partial information available for the app, but its assets include capsule and header images associated with the listing. The name specifically referring to a Network Test suggests that Bandai Namco may be preparing a test for the next Battle Operation title. However, details about the test itself have not been revealed.
Bandai Namco has not officially announced Mobile Suit Gundam Battle Operation 3, so the listing should currently be treated as a leak rather than an official reveal. The SteamDB entry also does not confirm whether this will be a completely new sequel or a major rework of the existing Mobile Suit Gundam Battle Operation 2.
The timing is particularly interesting, as Bandai Namco is planning a livestream celebrating the 40th anniversary of Gundam games later this year. While Battle Operation 3 could potentially be revealed during the event, there has been no confirmation connecting the two.
For now, the SteamDB listing provides the clearest indication that something called Mobile Suit Gundam Battle Operation 3 Network Test exists within Steam's backend. With the listing first appearing in July and receiving another update in September, fans will likely be watching closely for an official announcement from Bandai Namco.
