I’ve played this mission a few times tonight and got super samples (SSs) 3 times. They don’t spawn in every mission.

So far, every single time it was on the outer “ring” of the map (never in the dark corrupted circular area around the center).

Some tips:

• You can know right from the start if SSs are present by checking your sample list
• If you know some are present, focus your search on the outer area.
• Bring a Jump Pack - it lets you get to higher ground to spot the SS rock more easily, helps you to evade mobs and increase your movement speed.
• Make it a priority to find the samples and when you do, go directly to extract and drop them there before starting the mission. There are some deep holes in the ground on some maps (easy to fall into if it’s night) that you might not be able to jump out of even with the jump pack - you don’t want to lose your samples in there. Afterwards, you’ll have the option of extracting with the samples even if you fail the mission because you’re short on time.
• I’ve recall seeing a video that mentioned if you quit the game mid-mission (not return to the ship) and replay the same mission, you get the same map, so if you have a map you know has SSs and you haven’t found them, you can quit and retry the mission to search for them again. I don’t know if that’s still true.
• Using Scout Armor might help you to find them more easily (I tried but couldn’t get the hang of it in my attempts so far though) - See this video for more details.

My loadout has been:

• Incendiary Breaker (one shot to eggs will destroy them with fire damage)
• Light Scout Armor
• Redeemer
• Impact Grenades
• Jump Pack
• Orbital Gas Strike - to clear mobs following me
• Orbital Railcannon Strike to get rid of Bile Titans
• Orbital Laser Strike to get rid of Bile Titans
• Stamina Booster

Edit:

I ended up collecting 115 super samples (used 15 along the way) while this mission was available.

The video on locating SSs was somewhat accurate- the Scout passive sometimes marks the SS chicken leg rock as a point of interest, but usually it didn’t for me.

On the other hand, it was right that the SS rock is visible on the minimap (middle and highest zoom levels) and you can learn to spot them with practice. In the end, I didn’t need the scout armor to confirm the rock’s location - I could find it by looking for it on the map and I was right over 90% of the time.
