You looking for a starter base location or mid to late tier ?

mid and late tier bro

Check out 31, 32 on the map.

u know other? for large base

73,40. Just don't make the mistake I did and build on the nice flat cliff sided spot that will ruin the metal spawn. Easy water, crystal, organic polymer, narcoberries, harvestable spoiled meat and animal faeces and a highish level ( usually purple ) drop within easy reach. Pretty on the edge of the desert too.
