What exactly does the Anti-Materiel Trait allow? Can you destroy Scenery with it or is it just for certain missions?
Certain missions require it to complete objectives, other missions allow you to get into the Objective Room without opening all doors, and then there's the scenery optional aspect - you can agree with your opponent that scenery are destructible. The exact nature of destructible scenery doesn't seem to have carried over to N3 as it wasn't used much, but basically you'd assign ARM/BTS, STR and number of hits a building could take before collapse. If you defeat a wall you'd make a narrow access point ("door") there and if you did enough holes the building would collapse and create a zone of difficult terrain and saturation (if I recall correctly)
