How to complete the Bounds Testing Milestone in No Man’s Sky Leviathan Expedition

gamepur.com:

After surviving your first few moments in the Leviathan Expedition, only to have to kill yourself in order to repair your Starship, you’ll eventually be directed to meet Specialist Polo on the Space Anomaly. This leads into the Bounds Testing Milestone, where Polo offers up three separate ‘Loop Research’ missions to recover Ancestral Memories, Liquid Sun, and Somnal Dust. You only need to complete one to reach the Milestone, though they all contribute to the ongoing community targets. However, with the Somnal Dust mission requiring a risky trip to a Derelict Freighter, that’s probably best left alone to begin with ― which leaves you with two options.

To gain the Ancestral Memories you simply need to befriend some of the local wildlife by feeding them, which can make this the quickest and easiest option if you get lucky and find yourself among a herd of friendly animals. To get some food you just need to craft (or buy) some Creature Pellets, with Carbon one of many options to make them. Once happily fed, you can interact with them to get a few options, including the choice to adopt them as a companion which can be a great way to turn a predator into a powerful ally if you can bait them into a feast.

For the purposes of this mission, you obviously need to go for ‘Harvest Ancestral Memories’, which will see 15 of them sucked into your inventory. You need 200 in total, so you’ll have to repeat this at least 14 times, but the good news is that you can reuse the same animal after a short cooldown period, while having three or four creatures to bounce around will also speed things up a lot. Once you’ve hit the quota, you’re good to return to Polo
