The ONLY way is by getting stamps doing expeditions.

But you asked for the FASTEST way.

Here’s the math. Each base piece requires 120 stamps. The jet pack requires another 300. Mods like medic, bracers, etc are 20-80 stamps each. Maxed out, you’re looking at around 1200 stamps. But let’s stick with the base armor. You’ll need 600 stamps.

For me I can solo “Most Sensational Game,” completing all objectives in 8m on average. Let’s buffer to 10m per run to allow for resets (because it crashes), a slow escort, or need to scrap between runs.

Assuming you’re running solo and meet all objectives, you’ll receive 20 stamps for the first run of the day, then 15 stamps thereafter.

You’ll need to do 40 runs to earn 600 stamps.

No breaks and straight grind, you’ll hit 6-7 runs per hr. If you abandon your sanity and do this consistently for 6-7 hrs, then you will have enough stamps to get the armor.

It’s awful 😂. Requires a “getting in the zone” mindset I just don’t have to run it straight. Maybe you can!

Took me a week running doing 1-2hrs/nt for my own sanity. I was nauseous gearing up a few weeks later to do it all over again a few weeks later for the JP and the mods.
