Metal Wall
Defense Building • Tier 2
Overview
Metal Walls are reinforced steel barriers that provide serious protection against the increasingly dangerous creatures encountered in mid to late-game StarRupture. With 2000 HP—four times the durability of wooden walls—these industrial-strength fortifications can withstand sustained attacks from even the most aggressive alien species. Metal Walls are the standard defensive structure for established bases, offering the perfect balance between cost and protection. Their steel construction makes them resistant to fire, acid, and explosive damage, while their modular design allows for easy integration with turrets, gates, and other defensive systems. Upgrading from wooden to metal walls is a critical milestone in base security.
