Successfully completed a base defence with no damage to any rooms, no troop losses.
However afterwards every room was marked trashed and needed repair.
My team: (flown in rather that barracked at the base) 2 snipers, 1 assault, 1 scarab. The pandorians all dead except two crabmen who escaped after losing their guns.
fwiw base had a containment facility but no captures yet, also mist repeller and all the other basic amenities.
This is fairly run breaking mid-early game on legend as it’s 1000s of materials to repair. Especially if you don’t notice until after you’ve saved.
