The world's puzzle, answered
- From wave 50 every Hailstorm Cyclop on screen is a Resonator: every 6 seconds it pulses, telegraphed for the last second, and stuns you for 1.2 s at any range. Auto-fire and melee both stop
- It also bleeds you through the shield, so kill it fast; its first pulse lands 6 s after it comes within attack reach
- Stun Dodge and Stun Recovery soften the pulse. A stun cannot be refreshed while it lasts or during the short recovery after it
- When a stun ends, Counter Attack opens for free, so a Counter Attack build profits from the pulse
- Worlds 10 to 12 keep the Resonators
