Deep Sea Biomes
| Biome | Depth | Required Tube | Key Fish |
|---|---|---|---|
| Forgotten Deep | 0-100m | Starter | Cod, Salmon, Tuna |
| Ancient Sands | 100-200m | Pufferfish | Swordfish, Ancient Shark |

Deep Dive Tips
- Plan your oxygen route before dropping
- Bring the best gun you can reasonably afford
- Watch navigation in Crystal Caves and other tight areas
- Use visual landmarks instead of panic-turning in deep darkness
- Sell frequently instead of risking a loaded run
Warning: Deep biomes punish sloppy route planning. Greed is usually what kills a strong run, not weak stats alone.
Sunken Wilds Progression Context
Recent guide coverage keeps using Sunken Wilds as the endgame comparison point for tubes and route quality. The practical takeaway is simple: once you are pushing those routes, Wild Tube and Banana Tube become the names players search for, and your gear choices should be judged by repeat-route efficiency rather than by one isolated stat line.
- Do not force Sunken Wilds style routes on midgame oxygen gear
- Upgrade tube depth and oxygen before you chase tiny speed wins
- Use stronger artifact builds only after your route is already stable
- Treat endgame gear as a route package: race, tube, gun, artifact loadout
