After completing the mission "I Know It When I see It", C3n50r807 will send you to track down some ill-gotten copies of the latest ECHO sims.
True Vault Hunter
Gear: Sniper Rifle
After talking to C3n50r807, leave the refinery and you'll find that your destination is actually the camp below the refinery. When you get to the camp below, clear out the first part of the camp using the guns on your skiff. When they have been destroyed, check to the right to find a pass that leads further in.
This will take you to another camp in the rocks. There are five floppy disks scattered around the camp but unfortunately, they are being held by the various pirates and you have no way of knowing which ones. You can fight from here but you may also notice a large dish in the camp. You can also climb up the connecting posts to sit above the middle of the dish. This will give you a great vantage point and limit access to you by melee enemies but the cover isn't so great up here. You'll have to decide on the trade-offs.
Kill all of the pirates in this camp and you should easily find the five floppies you are looking for. When you have them all, take them back to C3n50r807 for your reward.
