Version Information
Steam Patch Notes
Official update history
Greetings, Commanders!
[p align="start"]Following the release of Mechabellum 2.0, we’ve gathered a lot of incredibly useful feedback. The development of our next major update is currently in full swing. However, before rolling out our next major update, we need to make a few minor adjustments. This update primarily focuses on balance for the \[Standard Versus] mode. We expect to roll out a balance patch for \[Star Expedition] very soon as well.[p align="start"]Standard Versus - Balance Adjustments
Void Eye
\[Suppression Shots]: Cost 100 → 150
Developer's Note: After our last base stat buffs to Void Eye, the 100-supply price tag for this Tech is a bit too cheap.Vortex
\[Machine Learning]: Cost 200 → 50
Developer's Note: We were too conservative with the numbers for this new Tech in the previous patch.Sabertooth
\[Anti-Air Missile]: Damage 2000 → 2500; Cost 200 → 100
Developer's Note: Similar to \[Machine Learning], we were a bit too cautious with the numbers for this new Tech in the previous update.Starter Packs
\[Void Eye & Fire Badger] Player HP modifier +200 → 0
\[Void Eye & Tarantula] Player HP modifier +200 → -100
\[Vortex & Tarantula] Player HP modifier +400 → +600
\[Vortex & Fire Badger] Player HP modifier 0 → +100
\[Vortex & Mustang] Player HP modifier +200 → +400
\[Vortex & Sledgehammer] Player HP modifier +300 → +500
Developer's Note: Recently, we received some feedback that Void Eye is too strong. In our stats, Void Eye's overall win rate and pick rate are close to average, but some Starter Packs containing Void Eye have notably high win rates. We therefore decided to nerf those Starter Packs first and will continue to monitor Void Eye's performance closely. At the same time, because Starter Packs containing Vortex have performed slightly worse than average, we decided to give them an HP buff.Unit Drop
Rank 3 Vortex will no longer appear in Unit Drop on Rounds 2 - 4
Bugfixes
Fixed an issue where some units were not receiving correct buffs from reinforcement cards in \[Star Expedition].
Fixed a Leaderboards performance issue.
Fixed multiple issues that could cause data errors.
Fixed multiple issues that could cause unit animation errors.

Commanders,
In yesterday's 2.0.0.3 patch, an incorrect configuration related to the Star Expedition difficulty was accidentally pushed live. As a result, many players encountered extremely difficult enemy lineups that were originally intended only for the top 20 players on the ladder.
This issue persisted for about 19 hours, meaning many of you experienced a massive and unintended spike in Star Expedition difficulty during this period.
To completely resolve this issue, we will be performing server maintenance. The maintenance is expected to take approximately 1 hour and will begin at the following times:
UTC: 11:15 AM
PDT (Pacific Time): 4:15 AM
EDT (Eastern Time): 7:15 AM
CEST (Central European Time): 1:15 PM
CST (Beijing Time): 7:15 PM (19:15)
We sincerely apologize for the frustration this has caused. Going forward, we will learn from our mistakes and be much more careful with our update process. More rigorous rules will be implemented to prevent this kind of mistake from happening in the future. Thank you for your patience and understanding.
This update primarily focuses on Centurion and the Star Expedition mode. We are taking a more cautious approach to the balance of Standard Versus, so further Standard Versus-related changes will be gradually implemented after we have collected and analyzed sufficient data.
[p align="start"]Standard Versus - Balance Adjustments
Centurion
HP: 15000 → 16500 (+10%)
ATK: 1500 → 1395 (-7%)
Missile count: 4 → 2
Missile damage: 800 → 2000
Splash Radius: 7 → 5
Scatter Radius: 20 → 0 (More stable performance, but overall clustered-unit-clearing ability is reduced)
Minimum Attack Range: 60 → 45
Attack targets: Can now attack Aerial Units
Cost: 200 → 250
Developer's Note: After the buff in the previous patch, the Centurion's pick rate increased significantly, and its overall performance has slightly exceeded our expectations. In this update, we tweaked its stats — slightly sacrificing its base attack in exchange for further improving its survivability, allowing it to occasionally serve as a frontline tank. Furthermore, we reworked \[Homing Missile]. The adjusted missiles have a reduced Splash Radius and significantly increased single-target damage, which means its efficiency in clearing clustered units will decrease, thereby limiting the viability of mass Centurion strategy. As compensation, this Tech has now gained anti-air capabilities, allowing the Centurion to retain some anti-air presence even in Melee Mode.Sandworm
\[Anti-Air]: Range modifier +20 → ATK modifier +30%
Star Expedition - Balance Adjustments
[p align="start"]The adjustments in Star Expedition mainly focus on buffing underused units and Techs.[p align="start"]Centurion

Minimum Attack Range: 60 → 45
Attack targets: Can now attack Aerial Units

Reduced the probability of consecutively matching against the same opponent player's lineup.
[p align="start"]Bugfixes

Mechabellum 2.0 has been out for a week now! During this time, we have collected a lot of interesting suggestions and feedback about \[Standard Versus] and \[Star Expedition]. Your feedback has been very inspiring. Many related new features are already in development, and we will also release a new, separate Balance Update soon. Meanwhile, we want to fix some known issues first and adjust the difficulty of \[Star Expedition].
The 2.0.0.2 update will take place at 10:00 UTC (06:00 Eastern Daylight Time, 12:00 Central European Summer Time) on Tuesday, September 29th, with approximately 1 hour of server maintenance. Below is the content of Update 2.0.0.2:
Star Expedition - Difficulty Adjustments
We have readjusted the matchmaking rules for enemy lineups. 70% of players will find the Expedition mode easier; the experience for high-tier players will remain largely stable, and the top 1% of elite players will experience an increase in difficulty.
Developer's Note: The enemy lineups you face in Star Expedition are snapshots of other players from your own matchmaking tier. Lower-tier players will match against a higher proportion of lineups from players who lost their matches, while higher-tier players will face more lineups from players who won. With this adjustment, we have further increased the ratio of lineups from defeated players for lower-tier players, and simultaneously increased the ratio of lineups from victorious players for the top 1% of players. Mechabellum currently sees hundreds of thousands of active commanders hitting the battlefield every month — so if you feel the mode has become harder after this update, it is highly likely because you are already among the top 1% of elite players worldwide!Elite Battle Contracts Now Available on Steam
DLC including \[Royal - Phoenix], \[Royal - Sabertooth], \[Dieselpunk - Steel Ball], \[Dieselpunk - Overlord], and the \[Golden Age Bundle] are now available on Steam for purchase. Thank you for your support, Commander!
Developer's Note: Due to platform scheduling, the DLCs will be available on the Epic Games Store on September 30th.Bugfixes
Fixed an issue related to Sandworm
Fixed an issue related to the Experimental Death Knell
Fixed several issues related to reward distribution
Fixed several display issues

Standard Versus Mode - Balance Adjustments
Centurion
ATK: 1401 → 1500 (+ 7%)
\[Melee Mode] Cost: 200 → 100
Developer's Note: Since the update was released very recently, we have not yet collected a sufficient amount of data. Early data indicates that Centurion is slightly underpowered, and this buff will increase its pick rate, which will help us gather relevant data more quickly. We expect to continue making adjustments to Centurion in the near future.General Optimization
Optimized the layout and animation effects of some interface elements.
Optimized the default camera position for some units in the hangar.
Bugfixes
Fixed the issue where mirrors of some high-level players failed to load correctly in \[Star Expedition]. This bug fix will have little impact on most players, but may increase the game difficulty for players ranked in the top 50 of the Ladder.
Fixed an issue where the Centurion's rifle was not correctly consuming ammunition under EMP.
Fixed multiple display issues.
