Where To Find the Depot Office Key

Head northwest of Plainsong to find this Relic Ruin, then go over to the west side of the building to find a rusty old carriage. Use your Pullcaster and pull it back as far as it’ll go on the other track, then interact with the switcher to change the tracks over to the Straight Track. Go back over to the carriage and pull it with your Pullcaster again until you reach the end of the track and climb up.

Where To Find The Code Depot Office Door Code

Carefully walk along the rope and pick up the Depot Office Key, then shoot the lock on the ladder in the corner and climb up. Scan the Construction Year Datapoint and you’ll gain a hint about their whereabouts of the code for the door. Jump down behind the datapoint and take a look at the side of the building to find several numbers. If you flip the number six so its upright it’ll make out the combination, 1923. Head back up to the door and interact with it to insert the key, then put in the code 1923 to unlock it.

(1 of 5) Shoot the lock on the ladder and climb up

Use the zipline to reach the room opposite, then use the Igniter on the Firegleam to break a hole into the wall. From here, go outside and use your pullcaster to pull the carriage back past the switch, then interact with the switch to change over to the Curved Track. Now pull the carriage into the building through the recently created hole. Finally, hop up on the carriage and climb up the pillar to reach the Stanfort Days Ornament.
