"Get power core" is an objective in the Story Mission The Road to Sanctuary in Borderlands 2
Walkthrough[edit]
Head to the West from where Reiss was/is. You will find a massive Bloodshot encampment here: Windbreak Camp. Time to start slaughtering Bandits. Try to snipe or get some ranged attacks against the Bandits from the walls by the edge of the camp. If you are lower level for this encounter, you will regret being so exposed quickly.
Start killing the Bandits inside the camp. One of them will drop the Power Core. Grab it and you will be prompted to head for Sanctuary
