With time to kill during their travel back to the front lines, Max got to work analyzing and optimizing their new complement of Mecha as Sylvie finished them.
Unlike the ship itself, the alloys weren't quite primitive. Instead, they were mostly ceramic armoured, which was energy efficient to produce, despite its complex structure, with the downside that it was brittle and considered a wear item, replaced after battle.
Unlike the Mecha that Max was used to, which were repaired and maintained with the same basic structure for decades or even centuries, these were designed to be modular and easy to section out and rebuild between engagements.
As long as your repair bay had the parts, you could have the whole armour set and a limb replaced in under an hour.
