Crush Depth

Submarines

A submarine's Crush Depth is determined by two factors - the number of hull upgrades, and if its class is set to Deep Diver or not.
The default crush depth value is 3500 meters. Hull upgrades give an additive bonus of 6% extra crush depth per upgrade level, and the Deep Diver class gives an additional bonus of 20% to the submarine's crush depth.
Therefore, the equation for the submarine's crush depth is 3500 * (1 + (upgradeLevel * 0.06)), or 3500 * (1 + (upgradeLevel * 0.06) + 0.2) for a Deep Diver.

Characters

Crush depth for characters works slightly differently.
The maximum allowed depths for characters with different gear/talents/afflictions are listed below. The highest depth value takes priority.

• Default - 0 meters
• Diving Suit - 4,000 meters
• Combat Diving Suit - 6,000 meters
• Slipsuit - 6,000 meters
• PUCS - 6,000 meters
• Abyss Diving Suit - 10,000 meters
• Water Prankster with Clown Power - Immune to pressure
• Pressure Stabilized - Immune to pressure

If a character descends below these depths without the proper gear, they will implode and die almost instantaneously.
