How to craft Standard & High Capacity Air Tanks
Answer first
Standard Air Tank (default blueprint): 2 Titanium, 1 Rubber, 2 Silver → ~75 s O2. High Capacity: find the recipe data card (PC Gamer: SW colony ruin past the drop-off; GameWith: ~210° toward Cicada wreck desk), craft Plasteel Ingot (2 Titanium + 1 Lithium at Processor), then Fabricator-combine Standard Tank + Plasteel Ingot → ~120 s O2.
Field notes
| Materials | Titanium, Rubber, Silver, Lithium, Plasteel Ingot |
|---|---|
| Tools | Fabricator, Processor |
| Depth / zone | Shallow → SW colony ruin desk card |
Steps
- Farm Silver (north Old Habitat caves) and craft Rubber (2 Lucifer Rotsacs) for the Standard Tank.
- Craft Standard Air Tank at any Fabricator: 2 Titanium, 1 Rubber, 2 Silver — equip it (~75 s max O2).
- Bring Air Bladders / mobility; head southwest from the Lifepod over the seafloor drop-off (GameWith also cites ~210° / Cicada wreck desk).
- Enter the ruined colony structure; pick up the High Capacity Air Tank recipe data card from the desk (scan Processor / Room cards if present).
- Gather Lithium nearby if needed; build/use a Processor to craft Plasteel Ingot (2 Titanium + 1 Lithium).
- At a base Fabricator: Standard Air Tank + Plasteel Ingot → High Capacity Air Tank (~120 s O2).

Checklist
- Standard Air Tank equipped
- High Capacity recipe data card
- Plasteel Ingot crafted
- High Capacity Air Tank equipped
Version differences and limitations
- Landmark wording differs (SW colony ruin vs Cicada wreck desk at ~210°) — both describe a southwest deeper colony ruin desk card; confirm in your build.
