Sound Cannon
Break line of sight during the sound cannon’s charge. Liquid only blocks its effect when exactly one of the player and cannon is submerged.

Recognize the charge
Sound cannons appear in Wasteland and Where We Must Reach. Unlike a turret fixed to a horizontal firing line, a cannon can rotate toward the player. The community entry describes a five-second charging sequence with a rumbling cue and a targeting arc that shifts toward red. Use the warning to break the firing path. Continuing toward the machine because it has not fired yet spends the very interval that makes avoidance possible.
Cover and water change the blast
The documented targeting check uses a single line toward the player, so even a tile of suitable cover can interrupt it. Scrap metal or scaffolding is one suggested way to create that cover when terrain offers none. Water has a specific conditional effect: the blast does not affect a player when exactly one of player and cannon is submerged. Both submerged is the dangerous case, with stronger effects; jumping into a pool is therefore not a universal solution.
A hit is more than hearing loss
The listed ordinary blast includes hearing loss, head pain, reduced brain health and consciousness, internal bleeding, reduced breathing and muscle damage across the limbs. A blocked blast can still reduce consciousness, according to the same page. That makes the health panel useful even after you believe cover worked. Treating only the ear icon can miss the blood or breathing problem caused by the same attack.
Recovery and drops
The entry associates procoagulant and L.R.D.-type devices with internal-bleeding treatment, while a chest drain addresses the resulting hemothorax rather than the original cause. Helluce also raises temperature, relevant in hot Wasteland conditions. Read individual item instructions before combining treatments. The cannon’s current loot panel lists scrap-metal drops and a possible circuit board, so the earlier claim that it drops nothing was incorrect. Its 1500 health is a community value, not a promise that attacking it is the safest route.
