"Find Jack" is an objective in the story mission The Talon of God in Borderlands 2.
Walkthrough[edit]
Time to make your way on through Hero's Pass. There is a lot here and you have a lot you need to destroy. Head on through to the Guardian Slag Heap and you will find Loaders and Hyperion Personnel waiting for you through there.
Get on through and across the first bridge. At that point Brick and Mordecai will show up with the Crimson Raiders Carrier that they hijacked. Fight on through the Loaders. Jump the gap and head on forward through to the Emergency Supply Cache. Get on through to the first 2 section bridge.
On the far side of the bridge you will find a shield blocking your way. On the top of 2 pillars you will see 2 Auto Cannons that are shielded. There are also a number of Loaders to deal with. You clear out the Loaders with Brick while Mordecai gives ranged support from the carrier.
When the Loaders and Cannons have been taken out, Brick will call you over to him. Loot the area and head over there. He will jump over to the carrier. The carrier gets taken down just a little after that. Press on forward through the Loaders into Drift Mouth Access. After the Loaders comes a Constructor. Press on through there.
Go on across the bridge, deal with the Commandos quickly. Turn to the right from there and look at the next section. There is at least 1 Super Badass Loader with numerous other Loaders in the area firing on you.
Things do not get any easier as you close on the final stretch of this area. You will find yourself against a Badass Constructor waiting by the entrance to The Vault. Deal with it at a distance to make the fight easier. After that just go straight on forward to find the entrance. Head along the path inside the Vault of the Warrior to the elevator. Hit the button to be taken down into the lower portion of the Vault. Just head forward, using the Vending Machines for any restocks that you need.
