Hull Integrity
Hull Integrity is a feature that currently affects Seabases. When the player is building their seabase they should pay attention to the hull strength, as it drops each time the player adds a module to their seabase. Once the seabase's hull strength, or Hull Integrity reaches 0 the seabase will flood with water, much in the same way as the Cyclops floods.
A seabase starts with a base integrity of 10, however, this does not include the additional +2.0 the foundation adds. The depth of your seabase influences how quickly Hull Integrity is reduced, and a seabase above water does not influence Hull Integrity. There is no Hull Integrity in Creative Mode.
Module Integrity Values
Each module in a seabase changes the value of the hull strength. Here is a list of current modules and their base changes (x1.0 depth multiplier) to seabase Hull Integrity:
| Seabase element | Change to hull integrity | Notes |
|---|---|---|
| Foundation | +2.0 | |
| Corridor | -1.0 | |
| L-Corridor | -1.0 | |
| T-Corridor | -1.0 | |
| X-Corridor | -1.0 | |
| Hatch | -1.0 | |
| Bulkhead | +2.0 | |
| Ladder | N/A | |
| Reinforcement | +7.0 | +14.0 when built on the North, South, East, or West side of a room. This may be a glitch. |
| Window | -1.0 | |
| I-Corridor Glass | -2.0 | |
| L-Corridor Glass | -2.0 | |
| Room | -1.25 | The game rounds the displayed number up to -1.3, but it is functionally -1.25 |
| Observatory | -3.0 | |
| Moon Pool | -5.0 | |
| Water Filtration Machine | -1.0 |
Depth Multiplier
As you build deeper underwater, negative influences on Hull Integrity are multiplied.
- Negative changes are multiplied by the depth multiplier: a window that is built with a x1.5 depth multiplier will give -1.5 Hull Integrity (instead of -1.0).
- Positive changes to Hull Integrity do not vary by depth: a foundation will always give +2.0 Hull Integrity no matter how deep it is built.
- Anything above 100 meters does not affect the depth multiplier.
Formula for depth multiplier:
M = Depth Multiplier d = Depth
if d <= 0, M = 0 (There is no change to Hull Integrity above the water)
if 100 > d > 0, M = 1.0
if d >= 100, M = ((d - 100)/1000) + 1.0
What this actually means: Every meter after 100 will add .001 to the depth multiplier.
Depth Multiplier Chart:
Please note that the depth multiplier changes every meter, not just at the increments in the table. For example, a depth of 276m would have a depth multiplier of x1.176.
| Depth | Depth Multiplier |
|---|---|
| <= 100m | x1.0 |
| 200m | x1.1 |
| 300m | x1.2 |
| 400m | x1.3 |
| 500m | x1.4 |
| 600m | x1.5 |
| 700m | x1.6 |
| 800m | x1.7 |
| 900m | x1.8 |
| 1000m | x1.9 |
| 1100m | x2.0 |
| 1600m | x2.5 |
| 2100m | x3.0 |
| 2600m | x3.5 |
| 3040m | x3.94 (Max Depth) |
