Mechabellum Update 1.9.1.3 Patch Notes (Feb 27, 2026)

Mechabellum's update 1.9.1.3 landed on February 27, and if you've been grinding into Round 5 and beyond, you'll feel the difference. The developers specifically called out Rhino performance and late-round optimization as the headline fixes here, with a note that further optimization work is already in the pipeline for the coming months.

The balance side of this patch is deliberately light. The team is clear that these adjustments are minor, designed to set up the new unit arriving in Season 7 rather than shake up the current meta. Mustang gets a mention in the notes, so expect that to get some attention from the competitive crowd.

This is a maintenance patch more than a meta-defining one, but smoother late-game performance is exactly the kind of fix that makes long sessions less frustrating. Season 7 is clearly on the horizon. Full patch notes below.

Performance Optimizations

• Optimized the performance of Rhino.
• Optimized the performance of later rounds.

Developer’s Note: Performance in Round 5 and beyond has been noticeably improved in this patch. We expect to release further optimization updates in the coming months.

Balance Adjustments

These balance adjustments are minor, mainly to lay the groundwork for the new unit coming in Season 7.

Mustang

• [Culling Rounds] Execution threshold increases per additional Level: +150 → +200

Developer's Note: The adjusted Culling Rounds will make it easier for lv3 Mustangs to execute lv2 Crawlers.

Scorpion

• [Doubleshot] Price 200 → 100

Developer's Note: The adjusted Scorpion will be more effective against high-HP units.

Crawler

• [Subterranean Blitz] Damage reduction 55% → 50%
• [Loose Formation] Price 350 → 250

Developer's Note: There are now finally enough options to counter light units in the game. In the next few patches, we will start to make adjustments for light units like Crawlers and Fangs.

Bugfixes

• Fixed multiple visual issues
• Fixed an issue related to Mustang's [Culling Rounds]
