Prepare the Bag
The backpack holds 20 unequipped hardware pieces. Keep room for guaranteed guardian drops. Ryan’s Bench can help you salvage unneeded pieces, and the Account Stash can hold spares you want to keep. If you are doing Three-Floor Purge, pick up that Charter in Harbor before entering.
Manifest each guardian
Regular enemies fill stabilization. When the guardian manifests, let the party regroup and read the telegraph before spending its burst skills. A directional shield gives you a reason to change attack angle. Move out of mortar warnings and avoid pulling another pack into the fight.
Descend or extract
Use the descent gate after the first two guardian kills to continue through all three floors. The extraction gate returns you to Harbor. The server can collect remaining guaranteed hardware at the portal when there is room. If someone is down, reboot them before descent. A successful third-floor extraction completes the run and allows a qualifying Purge claim.
