Reduce the number of open problems

A solo player handles threat, navigation, inventory, and extraction alone. Do not add a new layer, unfamiliar Vessel, and high-value carry goal in the same test.

Choose one unknown and keep the rest of the run familiar. That makes a failure informative instead of merely expensive.

Solo space disappears quickly, so the retreat path must remain usable before contact.

Preserve movement and awareness

Avoid filling every slot with the first recoverable object. Keep enough capacity and visibility to react to a threat or a better find.

Use doorways, sightlines, and known return markers to prevent a fight from cutting off the only safe direction.

Treat a small extraction as progress

A short solo return can fund Outpost growth and reveal a stable rule. Repeating that route with one new variable is more useful than chasing a dramatic deep run every time.

Community solo advice is a starting point; check every tactic against the current patch and your own Vessel.
