Map turret coverage before the next attack

Build overlapping coverage, not isolated circles

Click the map to place the selected turret. The center marker represents the base core. Coverage rings use each turret tier's detection radius on a common map scale; they are for comparing placement and overlap, not terrain measurement.

Tier choice changes both damage and cost

The first defense turret hits harder per shot, while the second-tier tower fires much faster and reaches farther. Mix them only when the stability and power plan can carry both.
