Finding a Pressurized Cave (Rare location)
1. What the Pressurized Cave Is Like
One player describes finding a Pressurized Cave on Starfield (notably on Sirius I):
- The cave contained the collectible Freestar Captain’s Log 01 magazine, located outside near the entrance.
- Inside, the cave was dark, filled with equipment and dead scientists.
- Hostile creatures such as the Longhorn Scavenger and Hunting Brightcages attacked frequently.
- The cave environment was hazardous (e.g., radioactive water).
- Despite being labeled “Pressurized,” players could not remove their helmet.
- The layout was confusing, making navigation difficult.
2. How and Where It Spawns
Across the posts, players agree:
- The Pressurized Cave is rare.
- It appears on planets with:
- No atmosphere
- No flora or fauna
- Traits like Charred Ecosystem or Extinction Event
- Its spawn location seems partially random.
- It may appear on several planets, including:
- Sirius I
- Guniibuu I-A
- Bara I
- Ursa Minor I-A
Some players report better luck landing in the southern hemisphere, though this may be coincidence.
3. How to Find It Efficiently
Players recommend:
- Land on a qualifying planet (no atmosphere, Charred Ecosystem).
- Exit your ship and look around immediately.
- If you don’t see a cave nearby, relocate and try again.
- Do not waste time exploring the entire map.
- The cave may:
- Appear clearly labeled “Pressurized Cave” in the scanner
- Or appear as a generic “Cave” / “Natural” icon until approached (reports differ)
Overall Takeaway
The Pressurized Cave is a rare, randomly spawning point of interest on airless, devastated planets. It’s highly sought after because it contains the Freestar Captain’s Log 01 magazine outside the entrance. The most efficient strategy is repeated landing attempts on suitable planets rather than prolonged surface exploration.
