Okay, Firewall will be the final chip you get in the Great Mine. What makes this guide confusing is that it’s giving you teams equipped with chips that you can’t possibly have yet. 🤦‍♀️ But the truth is, you don’t need to have those chips to win. Just follow their team recommendations as much as you can. It’s working out fine for me. 👍🏻

Not sure of those 2 yet, the Data Retrieval chip is in Cloudford treasure chest 4. Check the Cloudford victory zone page, it shows how to get it. I’m assuming the other chips may be in chests in other locations?
