The one get rich quick scheme that stands the test of time is meteor hunting for Oort. All you need is a few points into health, 3 points into kinetic armor - maybe more when you can - and a T3 planet. Every time your on screen GPS dings from “Northwest of ???” to “Arrived” there is a very good chance you will have spawned a meteor.
Each meteor has a little chest inside with 1-14 Oort, and each Oort sells for 200c and up. That can be 2,000c from a single meteor! Then just take it to any paying request basket.
Use that money to upgrade your grapple and slingbow, there’s a lot more to it than that - basic healing bombs are nice, but those 3 points in Kinetic armor make you sooo much more survivable.
P.S. if it’s a Level 3 meteor you may die… dig a cave or something to hide in and pick mobs off.
