Gears 5 Jack Abilities Location Guide
Inside the Train tunnel there is a large enemy you have to kill. When it is dead, go into the train car and find the notes on the floor to start the upgrade quest.
Then you have to go to these two spots on the map and clear them out. When they are cleared out, search the area for a safe or a panel you can remove to get the items you need.
The quest starts here on the map and you have to then progress a bit before reaching the other two areas.
When you get to the next area, through the large Cog gate, you can go to two sub stations. Go to the east one first and read the note by the frozen body. This will give you the info you need to gain access to the northern substation on the map. Open the safe in the northern substation and you will get the Shock Trap upgrade.
You need to complete the Scavenger Secondary Objective line that includes finding several locations and clearing them out, and grabbing Circuit Board collectibles.
1. City Ruins – In the room just before the end of the ruins, there’s a circuit board on the desk. Pick it up for the first part of this upgrade.
2. Artillery Battery – You need to complete the Hanger story mission first. Clear the enemies, head inside, up the stairs. Circuit board is on the table
3. Cargo Shipwreck – Defeat the enemies, grab the circuit board from the corpse up the stairs at the back
