Oxygen upgrade
Standard Air Tank Guide
Air Tank searches are really route-math searches. Players are not just asking for an item; they are trying to stop dying on trips that are slightly too long.
Quick answer: Standard Air Tank is the first oxygen upgrade most players should prioritize before deeper scans, wreck interiors, or longer material loops. Craft it from 2 Titanium, 2 Silver, and 1 Rubber; after it equips, oxygen rises to 75.

Route status
First-hour route plus official Silver hotfix context.
In-game check
Fabricator recipe: 2 Titanium, 2 Silver, and 1 Rubber; equipped oxygen: 75.
Route and unlock plan
Colonist Bunker 1 Silver route, then return to the Fabricator.
Step 1
Build it before deeper wreck routes
Do not combine starter oxygen with interiors, long scans, and downward route pressure.
Step 2
Use the dedicated Silver route
The Colonist Bunker 1 Silver route covers the Angel Comb branch, red hatch, BioBed, and safe return.
Step 3
Craft from three starter materials
The recipe is 2 Titanium, 2 Silver, and 1 Rubber at the Fabricator.
Step 4
Pair with beacon discipline
Extra air helps, but it does not replace knowing the way out.
Step 5
Delay Rebreather assumptions
Treat Rebreather-style depth relief as a separate in-game check.
Player decisions
| Question | Status | Rule |
|---|---|---|
| First oxygen goal | High priority | Build the Standard Air Tank before ambitious scans or wreck interiors. |
| Recipe | Fabricator craft | 2 Titanium, 2 Silver, and 1 Rubber. |
| Oxygen result | 75 oxygen | The tank equips after crafting and raises the oxygen value to 75. |
| Co-op planning | Each diver matters | One upgraded diver does not make the whole team safe on a long route. |
| Depth pushing | Not enough alone | Extra oxygen helps route time but does not solve depth, heat, or vehicle limitations. |

Questions people ask
Should I build the Standard Air Tank first?
Yes, for most saves it is the first oxygen goal before deeper scans, wreck interiors, and longer material loops.
Does Standard Air Tank replace route planning?
No. Extra oxygen is a margin, not a license to enter every wreck without an exit plan.
Does the Standard Air Tank need Silver?
Yes. The Standard Air Tank recipe uses 2 Silver, along with 2 Titanium and 1 Rubber.
