In the big red warehouse by the sea, close to the train tracks, you will find a small container labeled D2.
If you are the first player to visit here, you can see that the door is boarded up. If this is the case, you can easily break this wooden barrier with Rock, which has 50 health.
Once inside, put your Electric Fuse in the box, and then immediately turn the outside switch located just behind the Fuse Box to the green position.
Then follow the cable from this switch, which will lead you directly to another container under the red hangar with the word H2 on it.
After that use your Green Keycard to open the door, and take the Blue Keycard along with the Crates inside.
