Metal Construction
Basic Technology • Tier 2
Overview
Metal Construction upgrades your building materials from fragile wood to durable steel, dramatically improving base defense and longevity. Metal walls have 4x the health of wooden walls, metal floors support heavier machinery, and reinforced doors resist creature attacks far better than wooden alternatives. This technology is essential for protecting valuable equipment and automated systems from destruction. Metal Construction also enables multi-story buildings and industrial facilities that can withstand harsh environmental conditions and sustained attacks.
