Shielded Wall

Shielded Wall is a defensive building that functions as a wall with an integrated energy shield. It occupies a larger footprint than standard walls and projects a force field that absorbs incoming projectile fire until the shield's health is depleted. The block combines physical block durability with a regenerating shield layer, allowing it to block sustained attacks more effectively than ordinary walls. Shielded Wall appears alongside other advanced defensive structures and is often used to form the outer layer of bases where concentrated, repeated projectile fire is expected.

The shield behaves like the force field produced by the Force Projector: projectiles that are absorbed by the shield register only single-target damage against the shield itself rather than dealing area or multi-hit effects through the shield. This means beam and explosive projectiles that would normally hit multiple tiles are stopped by the shield and contribute their damage only to the shield's hit points. Missiles launched by units are an exception: unit missiles ignore the single-target absorption rule and deal their normal damage against the shield, so missile-heavy attackers remain a threat. The physical wall portion still provides collision and slows or blocks ground units in the same way as other wall blocks.

Because Shielded Wall is based on an older, smaller Shielded Wall design, it preserves the conceptual separation of shield and block health while adopting a different footprint. It is one of the few wall-tier defensive blocks that lacks a 1x1 counterpart; along with Blast Door and Thruster, it exists only in its larger form. Use Shielded Walls where you need an extra layer of protection without committing to stationary Force Projectors: they occupy wall lanes and defend against prolonged volleys, but remain vulnerable to unit missile spam and to sustained damage that can exhaust the shield and then chip the wall's core.

• Place Shielded Walls at choke points and in front of important buildings to soak initial volleys and preserve interior structures.
• Support Shielded Walls with nearby power and repair infrastructure when available so the shield can regenerate and the wall can be maintained.
• Combine Shielded Walls with splash-damage defenses that target enemies outside the shield or with anti-missile measures to counter unit-launched missiles.
• Remember that while shielded projectiles are absorbed as single-target hits, once the shield is down attackers damage the wall normally; plan for backup layers or rapid shield regeneration.
