Release Schedule and Language Support
Starter Set 01 launched 31 October 2026 in Japan. Expansion Packs 01 and 02 landed the same month; Deluxe Set 01 followed in November 2026, with packs and deluxe sets scheduled through March 2027. Official rules are published in English, Japanese and Simplified Chinese.
Gundam Assemble launched as a rolling range rather than a single release day. The starter set arrived first, then deluxe sets and expansion packs spread across six months.

Starter Set 01's Japanese launch date is listed as 31 October 2026 on Bandai's product page. Deluxe Set 01 was originally scheduled earlier and was moved; the product page carries a 15 July 2026 notice about the change.
Why the stagger matters
The launch wave is the only one that gives you a complete game. Six units, eighteen Tactics cards, two scenarios and a map all arrive together in Starter Set 01, and Expansion Packs 01 and 02 add nine more unit cards between them on day one.
Everything after November is depth rather than entry. A group that starts in October will have 15 unit cards and two map layouts available; a group that starts in March 2027 will have the same core plus five more expansion packs and three deluxe sets.
Languages
The official Gundam Assemble site publishes in four variants:
- Japanese
- English (USA)
- English (other areas)
- Simplified Chinese
The quick-start manual on the site is the same document across the English variants, with US spelling and US MSRP on the American page. Bandai Hobby's wider site adds Traditional Chinese, Korean and Spanish navigation, but those are the parent site's languages rather than confirmed Gundam Assemble product languages.
Practically: if you are playing in English, the rulebook and cards in the US box are English, and the quick-start manual online matches it. Card images on the official card list are published in English and Japanese separately.
What is not translated
The two official card text corrections published in November 2026 are marked as Japanese-language notices on the rules page. If you are playing an English set, check the English card list rather than the notice for the corrected wording.
Age rating and packaging notes
Every product page carries the same three notes: intended for ages 15 or older, miniatures ship unpainted, and product specifications, price and contents are subject to change. The "images contain content still in development" line appears on promotional material for later waves.
Regional pricing
US MSRP runs $35 to $170. Japan list price is 3,500 yen for the starter and 9,000 yen for Deluxe Set 01, excluding tax. The price page has the full fifteen-SKU table.
Buying around the schedule
If you are starting now, the sensible buy is the starter plus whichever expansion pack your local shop has in stock. Later waves are additive; nothing in the March 2027 releases replaces an October 2026 purchase.
For what each release actually contains, see starter vs deluxe and the roadmap page.
Language of the cards themselves
The official card list publishes card images per language, and the English and Japanese printings are separate. That matters for two reasons: card text corrections are published against a specific printing, and a mixed-language collection can end up with two versions of the same card number.
For play, the language does not matter - the numbers and the card number are identical. For deck legality checks at an event, use the printing you will actually play with.
What to check when a new wave lands
- Card numbers, because promos and parallel cards carry their own numbers and change what is legal to duplicate.
- Scenario cards, because each box adds scenarios rather than rules.
- The rules page, because corrections accumulate there rather than in a new rulebook edition.
There is no announced second edition of the rulebook, so the quick-start manual plus the corrections list is the current ruleset.
