Metal Mosaic guide
Updated
Board game: Metal Mosaic is Drill in the official FAQ. Mechanics are folded below. This page does not assert an identical digital unlock path.
How this class enters a campaign
Open the box when your campaign instructs you. A retirement alone is not a verified Drill unlock. The unlock guide separates the known campaign rules from unverified individual requirements.
Builds
Editorial recommendation: budget the complete turn before selecting two cards. Check item timing, conditions and the solo add-on before assuming a combination works.
Questions
Drill spoilers: when does pressure change?
Printed pressure changes resolve at the end of the whole action, one card half. They are mandatory when a relevant part is performed, but are not costs: inability to lower pressure does not itself forbid the action. Modifier pressure effects are optional and wait until the triggering action ends.
Drill spoilers: what build and perk interactions matter?
Steel Piston's pressure change waits until the modified action ends. Recursion adds another change even to a double-change symbol. The three-mark perk loses cards you were about to play too. Editorial recommendation: plan pressure per action, and evaluate the full hand cost of that perk.
