OGame Version 13.0.0 Explained: What Changed, What Broke, and What You Need to Know
OGame 13.0.0 rewrote most of the game backend for speed and stability. Here is the real timeline, the gameplay changes that matter, and the one warning worth knowing before you touch your Lifeforms or Technology Tree.
OGame Version 13.0.0 is the biggest technical update the game has had in years, a near-total rewrite of the backend rather than a normal content patch. If your fleet slowed down, your probes started surviving fights they used to lose, or an add-on you rely on suddenly broke, this update is why. Here is exactly what changed, based on the official changelogs, not guesswork.

What Actually Changed Under the Hood
Version 13.0.0 is described by the OGame Team as a "mostly rewritten codebase covering nearly all OGame features," built around a new centralized data system that replaces years of fragmented, feature-by-feature backend code. The practical goal was fewer backend calls per action and a more consistent foundation for future development, and it shows up as measurably faster loading, most noticeably on the Empire overview and the Highscore page, both of which were previously among the slowest pages in the game.
This was not a quick patch. The update spent over two months on the public test server ("Singularity," opened May 13, 2026) going through more than 20 build cycles before the OGame Team considered it stable enough for live universes.
The Real Rollout Timeline
Rather than flipping every universe over at once, 13.0.0 rolled out in four separate batches, each about a week apart:
- Batch 1 - July 20, 2026, 10:00 CEST
- Batch 2 - July 23, 2026, 10:00 CEST
- Batch 3 - July 30, 2026, 10:00 CEST
- Batch 4 (final) - August 13, 2026, 10:00 CEST
As of the final batch, every universe is running 13.0.0. The staggered approach let the OGame Team catch and patch issues on a subset of universes before the last group ever touched the new code.
Gameplay Changes You Will Actually Notice
Most of 13.0.0 is invisible backend work, but a handful of changes directly affect how you play.
Espionage probes no longer auto-lose
Before 13.0.0, a lone Espionage Probe fleet could lose a "battle" it had no real business fighting simply because it was the only ship type present. That rule is gone. Battles are now instantly resolved (rather than fully simulated) only when one side's combined attack power exceeds the other's by more than 10,000 times, otherwise a normal combat round plays out. If you rely on probes for scouting, this is worth understanding properly. Our Espionage Guide covers the full counter-espionage mechanic this change interacts with.
Being spied on no longer shows you the report
From the 1 July build onwards, a player who has been spied on can no longer open the full espionage report by sharing it or by viewing it in galaxy view from a different planet. That route used to exist, and it let the defender see exactly what intelligence the attacker had gathered. It is closed now. You still get the message telling you a scan happened — you just no longer learn what it returned, so treat every scan as if the attacker saw everything.
The fuel-saving bonus is fixed
The global fuel reduction bonus from research and officers was capping incorrectly at 30% instead of its intended 90%. That bug is fixed in 13.0.0, so fleets that rely on a stacked fuel-saving setup for long expeditions or fleet saves will see real deuterium savings that were not actually being applied before.
Bashing limits now correctly cover alliance members
The rule preventing repeated attacks on the same weaker player (the "bashing limit") was incorrectly being bypassed for buddies and alliance members. It now applies correctly across the board.
Resource production after vacation mode or planet switching
A bug where resource production figures did not update properly after returning from vacation mode, or after switching between planets, has been fixed, so what you see on screen now reflects what is actually being produced.
The One Real Warning From This Update
The OGame Team flagged a genuine, non-reversible risk during the rollout window specifically: deactivating Lifeforms or resetting a Technology Tree while your universe was being migrated to 13.0.0 permanently deleted the hidden configuration data behind those features. This only affected players who took one of those two actions during their universe's specific update window, and since all four batches completed by August 13, 2026, that window has now closed everywhere. If you did not deactivate Lifeforms or reset a Technology Tree during your universe's update batch, this does not apply to you.
Add-ons and Third-Party Tools
Because so much of the backend changed at once, most browser add-ons and userscripts were not immediately compatible with 13.0.0 and needed their own updates from their individual developers. If a tool you use, including Antigame, is behaving oddly, the first step is confirming you are running its current version rather than assuming the tool itself is broken.
If OGame Looks Broken, Do This First
A surprising number of post-update "bugs" reported after 13.0.0 turned out to be nothing more than a stale browser cache still serving old styling or scripts. Before reporting an issue, force a hard refresh: Ctrl+Shift+R on Chrome, Ctrl+F5 on Firefox or Internet Explorer, or a manual cache clear on Opera (Ctrl+Shift+Delete).
