Plot each threat by recognizing its polar coordinate and tapping the matching point on the radar.
1. Read The Signal
(r, θ) means radius from the center, then angle from the positive x-axis.
2. Tap To Fire
Tap or click the matching spot once. The turret locks, rotates, and fires automatically.
3. Expect Escalation
Later waves add radians and, on higher tiers, negative radii that map to equivalent locations.
