Ripper Drill sites in Borderlands 4 are one of many activities you can do across Kairos. Upon entering a site, you’ll face waves of enemies that you need to defeat to spawn the boss. It's a good way to farm weapons, including legendaries from bosses, and a lot of XP. You can start doing the activity from the early game, but some of the boss fights can get challenging.
What’s more is that it’s an activity that you can do back-to-back using Moxxi’s Big Encore machine. That said, this guide will help you locate all the Ripper Drill sites in Borderlands 4.
