Gundam Battle Operation 3 Mobile Suit List: What We Know So Far About the Roster

The Roster Question Everyone Is Asking

The most-searched question about Bandai Namco's next free-to-play mech shooter still has no official answer: there is no confirmed Gundam Battle Operation 3 mobile suit list yet. That doesn't mean the wait is empty. A SteamDB entry for a "Network Test Version" surfaced in late September 2026, and a live stream celebrating the 40th anniversary of Gundam games was planned around the end of October — two signals that a formal reveal is close.

For players already planning their first hangar, the smart move is to understand how Battle Operation rosters are built. That knowledge is the best preparation available while the Gundam Battle Operation 3 mobile suit list stays under wraps, and it will let you read the reveal trailer the moment it drops.

Is There an Official Gundam Battle Operation 3 Mobile Suit List Yet?

Short answer: no. As of October 29, 2026, Bandai Namco has not published a roster, a unit count, or even a full feature breakdown. What exists is a paper trail — a SteamDB registration for a network test build, plus the timing of the anniversary broadcast — reported by outlets like Gematsu in their coverage of the Battle Operation 3 network test listing on SteamDB.

That last row matters most. Anniversary streams are where Bandai Namco historically front-loads announcements, and a network test build existing in Steam's database usually means a public test is weeks — not years — away. When that test opens, datamined unit IDs are typically the first unofficial glimpse of the roster.

Why You Should Be Skeptical of "Leaked" Lists

Search for the Gundam Battle Operation 3 mobile suit list today and you'll find forum posts, AI-generated wiki pages, and clickbait slideshows. Community reports are worth watching, but treat any list without a Bandai Namco source as speculation. A useful rule: if a "leak" names exact costs, stats, and release dates for thirty units at once, it's fabricated. Real datamines arrive messy — internal IDs, placeholder names, missing models.

What Battle Operation 2 Teaches Us About the Roster Formula

Battle Operation 2 launched on July 26, 2018, and has spent years adding units in waves. Its structure is the strongest predictor we have for how a Gundam Battle Operation 3 mobile suit list will be organized. Every unit falls into one of three combat types, and that triangle shapes every match.

Beyond type, every unit sits in a cost bracket that gates it into match tiers. Cost roughly tracks era and power, so a low-cost grunt suit from the One Year War never shares a lobby with a late-UC ace machine unless the match rules allow it.

This tiering is exactly why a Gundam Battle Operation 3 mobile suit list will never be a flat alphabetical catalog. It will be a matrix of type, cost, environment (ground or space), and weapon loadout.

Likely Categories in the Gundam Battle Operation 3 Mobile Suit List

Battle Operation 2 draws from across the franchise, not just the original series. Expect the same franchise-spanning approach, with the Universal Century as the spine and alternate timelines as high-interest additions. The table below frames eras rather than confirmed units — no playable roster has been published.

A realistic expectation: the launch roster will be modest, focused on the Universal Century, with alternate-timeline suits added over time as live-service content. Battle Operation 2 followed exactly that curve — starting lean and growing for years.

The Units Most Likely to Headline the Launch

If you want a shortlist to watch, these are the franchise staples that have anchored nearly every Gundam game roster for two decades. They are not confirmed — they are the safest bets based on brand logic.

• RX-78-2 Gundam — the face of the franchise; almost certainly the poster unit.
• MS-06 Zaku II — the default grunt and the natural tutorial machine.
• RGM-79 GM — the beginner-friendly General that teaches beam rifle timing.
• MS-07B Gouf — a melee-forward Raid that showcases heat-rod combat.
• MS-09 Dom — hover mobility, ideal for demonstrating ground-vs-space differences.
• MSN-04 Sazabi and RX-93 Nu Gundam — the marquee high-cost rivalry.
• RX-0 Unicorn Gundam — the modern flagship for premium-tier appeal.

How to Build Your Own Hangar Plan Before Launch

You can prepare a hangar strategy without a single confirmed unit. The triangle, cost brackets, and map types won't change, so plan around them.

One practical tip from player experience in Battle Operation 2: new pilots who main a single Support unit get hunted relentlessly. Rotating between a General for frontline reps and a Raid for flanking reps builds matchup awareness faster than grinding one machine to mastery.

Reading a Reveal Trailer for Roster Clues

When the first proper trailer lands, watch for three things: which suits appear in the gameplay montage (likely launch units), which appear in a teaser stinger (likely post-launch), and which appear only as background wreckage (likely not playable). Studios are deliberate about this. A suit shown performing a unique animation — a funnel launch, a transformation, a beam saber clash — is almost always playable, because that animation had to be built.

Where to Find the Real Gundam Battle Operation 3 Mobile Suit List

Roster information will arrive in tiers of reliability. Knowing which tier you're reading saves you from building a hangar around a fabricated unit.

The single best habit: bookmark the official Gundam games portal and the game's Steam page, then check them after each major broadcast. Everything else is commentary.

FAQ

Has Bandai Namco published a Gundam Battle Operation 3 mobile suit list yet? No. As of October 29, 2026, there is no official roster. A SteamDB entry for a network test build and an anniversary broadcast window are the strongest signals that a reveal is imminent, but neither confirms specific units.

How many mobile suits will launch with the game? Unconfirmed. If the sequel follows Battle Operation 2's pattern, expect a focused Universal Century launch roster that expands through seasonal updates rather than a massive day-one catalog.

Will alternate timelines like SEED, Iron-Blooded Orphans, or The Witch from Mercury appear? Almost certainly, but likely as post-launch additions. Battle Operation 2 built its roster the same way — Universal Century first, alternate timelines layered in over time.

Where should I look for a trustworthy Gundam Battle Operation 3 mobile suit list? Start with official Bandai Namco channels and the game's Steam page. Reputable outlets reporting on official material come next. Treat datamines as accurate-but-partial and community roundups as entertainment until a primary source confirms them.

Which unit type should a new player main? Start with a General. It's the most forgiving type, it teaches the Raid-General-Support triangle from the middle, and it won't leave you helpless in either direction. Branch into a Raid or Support once you can read a match's flow.
