Creator's Notes Rahlo calls this "the best 1x1 open core" he could think of. He emphasizes it's "super nice and super easy" to build. He notes the symmetrical design prevents issues. The vending machine bunker baits raiders into a pseudo core on lower floors. All pieces place in stone initially, then upgrade selectively.
Best For Duo players wanting a defensible 1x1 with multiple peek angles and clean, low upkeep.
