When playing the game Voidtrain you going to have a quest “Find a way to open the door”, this is the way how to pass the quest.
How do you open the door in the Darkness quest?
In the same room where you have the animation and is the door, you going to see on the door 4 marks that are equal to 4 statues.
These 4 statues can be found in the same room, and you need to destroy them by using your gun.
Statue Number 1 location:
The first statues can be found in the right part of the door
Statue Number 2 location:
Statue number 2 is on the top of the table parallel to the door
Statue number 3 location:
Statue number 3 can be found near some boxes on the left part how you exit the door you come inside.
Statue number 4 location:
Statue number 4 can be seen on the table on the right part of the door you enter the first time in the room.
Now, after you destroy each statue, the door will be unlocked.
I hope this guide helped you pass this quest 🙂 Enjoy!
