MechaStellar Monthly Roster Update – SEP 2025 – METEOR + Balance Patch

Hello everyone, for this month’s update we are adding in the METEOR units from Gundam SEED. We also have a huge balance patch affecting various units, pilot traits, and the entire weapons arsenal. There are also various revisions to the core rules to to clarify various questions that have come up, as well streamlining movement and allowing for stronger versions of Flash and Iron Wall to allow for more survivability of units.

Unfortunately the balance patch is quite large so as of today only the rules and unit profiles for Gundam are complete. The roster update for Super Robots and Warships is planned for next week. Keep reading for a quick summary of changes. We’ll do in-depth posts next week as well to go over changes.
