SD Gundam G Generation ETERNAL 2026 Roadmap: New Units, Story Updates, Events & Future Content Guide
SD Gundam G Generation ETERNAL enters its 1.5th anniversary in July 2026 with a packed roadmap: F91 main story, 1,000+ units milestone, new history stages, E Simulator 0079, and a major Gundam Card Game crossover.
What Is SD Gundam G Generation ETERNAL?
SD Gundam G Generation ETERNAL is a free-to-play mobile strategy game developed and published by Bandai Namco Entertainment. Available on iOS via the App Store and Android via Google Play, the game lets players relive iconic Gundam storylines across generations while building custom squads of Mobile Suits and pilots. Since launch, the title has surpassed 9 million global downloads and recently crossed the 1,000-unit milestone — a roster drawn from dozens of Gundam anime, manga, and sidestory entries.
The game blends turn-based tactical combat with a deep collection system. Players assemble teams of pilots and Mobile Suits, each tied to specific Gundam titles, and progress through History Stages that recreate famous battles. A Generation Tower mode offers roguelike-style challenge floors, while limited-time events introduce exclusive units, story branches, and crossover content.
The 2026 Roadmap at a Glance
The July-through-September 2026 roadmap represents the most content-dense period in the game's history. Anchored by the 1.5th anniversary celebration and the Mobile Suit Gundam F91 main story addition, the roadmap spans new units, new History Stages, a brand-new event format, system overhauls, and a physical card game crossover.
Mobile Suit Gundam F91 and the Late Universal Century
The centerpiece of the summer 2026 update is the addition of the Mobile Suit Gundam F91 main story stage, arriving on June 30. F91 marks the beginning of the Late Universal Century era within the game — a period set after the events of Mobile Suit Gundam: Hathaway and the Mafty uprising of UC 0105.
In the F91 storyline, the Crossbone Vanguard launches a surprise assault on the Frontier Side colony cluster, triggering the Cosmo Babylon War. Players will experience this conflict through new story missions, with key units and characters from the film joining the roster.
New Units and Characters from F91
Character Adjustments
Seabook Arno and the F91 Gundam, both previously released during the half-anniversary campaign, received upward attack adjustments as part of this update, increasing their viability in current content.
1,000-Unit Milestone and Rewards
SD Gundam G Generation ETERNAL officially surpassed 1,000 playable Mobile Suits in its roster. To commemorate this milestone, all players received 1,000 diamonds through in-game mail. Additionally, the F80 Gunblade unit was distributed as a free reward through the F91 panel mission.
Stocking up on diamonds ahead of a packed banner schedule like this one is essential. Many players use Topuplist to purchase SD Gundam G Generation ETERNAL top-ups at competitive rates with instant delivery — a reliable option when limited banners and anniversary events stack up.
New History Stages Arriving July 8
Two new Gundam titles join the History Stage lineup on July 8, 2026, expanding the game's story content significantly.
Mobile Suit Gundam SEED Astray
The SEED Astray storyline follows the mercenary team Junk Guild and the two Astray units — Red Frame and Blue Frame — through sidestories that run parallel to the main Gundam SEED narrative. This addition brings new pilots, new Mobile Suits, and new missions themed around the Cosmic Era timeline.
Mobile Suit Gundam 0080: War in the Pocket
Set during the final weeks of the One Year War, 0080: War in the Pocket tells a grounded, character-driven story centered on the colony Side 6. The addition of this title brings iconic units such as the Gundam Alex and the Kampfer into the History Stage rotation.
E Simulator 0079 — A New Event Format
Launching in late July, E Simulator 0079 introduces an entirely new event type to SD Gundam G Generation ETERNAL. This event explores alternate history scenarios set during the One Year War (UC 0079), allowing players to experience "what-if" battles that diverge from the canonical Gundam storyline.
An official gameplay demonstration video was scheduled for release alongside the event, showcasing the mechanics and unit interactions unique to this format.

SD Gundam Side Story Rerun
The SD Gundam Side Story — a story event featuring the fantasy-themed SD Gundam universe — returns as a rerun in July, with a second rerun scheduled for August. This event brings exclusive units and story content rooted in the SD Gundam mythology, which exists as a parallel fantasy setting within the broader Gundam franchise.
August: Round Table Part 2 and Part 3
August delivers a major content drop with the simultaneous release of Round Table Part 2 and Round Table Part 3. These story events expand the Knight Gundam narrative arc, a fan-favorite storyline that blends Arthurian legend motifs with Gundam mecha design.
Releasing both parts simultaneously allows players to experience the complete arc without waiting for a sequential rollout — a first for the game's event scheduling.
September: WF Dual Story Event
September's headline content is a dual story event under the WF banner, focusing on the character Shara Acustica. This event introduces two interconnected story paths that players can progress through simultaneously, with unique rewards tied to each branch.
Gundam Card Game Collaboration — Eternal Nexus
In a first-of-its-kind crossover, SD Gundam G Generation ETERNAL partnered with the GUNDAM CARD GAME for a collaboration product line released on June 26, 2026. The crossover consists of two products:
Starter Deck: Generation Pulse [ST10]
Extra Booster: Eternal Nexus [EB01]
The tagline for the collaboration — "A battle that transcends generations begins with cards" — reflects the cross-generational nature of both products. Characters and Mobile Suits from multiple Gundam timelines appear as collectible cards, with specific card designs tailored for the GUNDAM CARD GAME's multiplayer modes.
Featured Cards from EB01
The Eternal Nexus booster includes a curated selection of cards identified by the EB01 numbering system. Nine sample cards were showcased prior to release:
