About
OverviewCrush Depth puts you alone at the controls of a submarine in an endless ocean, with leviathans lurking in the dark below. This guide covers how to move your sub, how to survive encounters with those creatures, which upgrades to prioritize, and how to gather the resources that make all of it possible.

Basic submarine controls
Step
In short
Getting comfortable with movement in shallow water is the only way to prepare for what waits deeper down.
You receive a submarine controller at the start of the game. Spend your first few minutes in shallow water so you can learn how the sub handles before pressure — and danger — increase. Slow, steady movement lets you notice your surroundings instead of rushing past them.
- Learn the movement controls practice steering until turning feels automatic.
- Adjust your camera swing your view around regularly so nothing sneaks up on you.
- Practice changing depth run through ascending and descending several times while it is still safe.

Upgrade priorities for early survival
TableThe upgrades you choose first shape how safely you can expand into deeper areas.
| Durability | makes the submarine harder to destroy, so a hit from a leviathan does not end your run immediately. |
| Oxygen supply | extends how long you can stay underwater before you are forced to retreat. |
| Movement speed | lets you flee threats faster and cover more ground during an exploration run. |
| Visibility | widens what you can see in dark deep-water areas, giving you more warning before trouble arrives. |

04
Gathering resources across depths
Tips
Resources are scattered throughout the ocean and are the only way to fund upgrades. Deeper zones offer more of them, but only a sturdier submarine can reach those zones safely.
Tips worth knowing
- Start every session in shallow water to collect easy resources before heading down.
- Only push into deeper zones once your durability and oxygen upgrades can support the trip.
- Return to base regularly to spend resources on upgrades.
05
Surviving leviathan encounters
Warn
Leviathans are large, dangerous creatures that appear in deeper parts of the ocean and will attack your submarine when you get close. Because the game is designed around evasion rather than combat, every second you spend near one is a second closer to losing your sub.
Worth watching out for
Keep scanning your surroundings constantly
spotting a leviathan early is the difference between escaping and taking damage.
Flee the moment one enters your view
do not hesitate hoping it will pass.
Stay in shallow areas while your sub is still underupgraded
leviathans are far less common there.
