|Claptrap - Meridian Outskirts||Cash, Rare Shield (Optional Objective)||10|
In order to begin this Side Mission you'll need to have started the Hostile Takeover Main Mission. After you've repaired Sanctuary and journeyed through Promethea, you'll end up in Fort Pissoff. Collect the Healers and Dealers Side Mission from Claptrap by interacting with the Bounty Board near the Catch-a-Ride station.
Meet Ace Baron
Once you've accepted the Side Mission you'll need to meet with Ace Baron. He can be found in his facility to the south-west of the map. After you've spoken to him you'll need to explore the Merdian Outskirts to find medical supplies.
Med Pack #1
Your first stop around Meridian Outskirts will be at a piller that has a ladder next to it which will allow you to climb up to Hardin. After you've spoken with Hardin you'll be given the choice to either threaten or pay him, make sure you pay him the $1000 to complete the Optional Objective.
Med Pack #2
Drop down from Hardins trailer and head up to the second waypoint where a Medical Technical will exit a garage to the edge of the map, take him down to receive the next set of medical supplies.
Med Pack #3
Collect the medical supplies from the Technical and head over to the third and final location. Once you arrive at the waypoint you'll notice there's a broken gate, head through and take out all the Ratchs that appear and collect the third set of medical supplies from a crate at the back of the room.
Med Pack #4
With all the other Medical Supplies collected from around the map it's time to head back to Ace Baron, once you arrive at his facility place all the supplies on the table. Unfortunately you still need one more pack so Ace Baron has volunteered to do it, wait for him to sit on the chair and press [R3]/[RS] on his arm to retrieve the last blood pack.
