So how about making the chance of recovering implants this way really low? like 5-10% or maybe even less. Or maybe a higher chance but you only really get to recover 1 or 2 if you’re lucky.
What this would do is encourage to haul bodies in droves, to get significant rewards.
Stash those bodies, freezer them up and haul them over once you have quite a few of them.
You could even not bother hauling them and just setting up a contract to sell lots of bodies to someone who wants to try their luck with implant removal, not saying the bodies would be worth a lot because of the low chance of retrieval but they would be worth something probably, depending on the desirability and stuff.
