Frequently Asked Questions
What material HP values are used?
Wood 250 HP, Cobblestone 600 HP, Reinforced Concrete 3,000 HP, Steel 8,000 HP. These are standard Alpha 21 values.
What counts as a support block?
Pillars, columns, and load-bearing walls that support multiple blocks above. Mark these as "Support" for a 1.5x HP multiplier in the score.
How is the score adjusted for height?
Each storey above 3 reduces stability by 5 points - taller bases need more support pillars to maintain integrity against demolisher impacts.
