This portion of the guide explains how to solve escape The Fortress with the help of the tank.
Your goal here is to locate all of the ingredients for ammo.
- Hint: Notes in (The Arsenal) are more important than you think.
Once inside, head down the stairs. Continue straight on and you’ll end up in the arsenal.
There’s a machine in front of you that has a shell ready for you, but you need to find the ingredients to make gunpowder. The sign in front of you details everything you need: sulfur powder, saltpeter, and milled charcoal.
On the table to your left, you’ll find a note saying that the saltpeter has been moved to the Quartermaster’s Stores. Worry about this ingredient later. First, find what’s already here.
The door in this room is blocked, so head down the hallway on your left. Careful, though, there’s a trap on the floor! Keep moving down the hall. The first door on your right (the blocked room) has charcoal for you on the right. Put it in the machine to the left and grind it into a fine powder.
Then, head back into the hallway and go right. This will lead you right into a dark room with a trap door blocking your way ahead. Now, you have to find a way to open it.
If you head towards the windows on your left and turn around, the key will be right on the dead man in front of you. Take it from his hand, then head back to the door to open it, but be prepared to run for cover.
Surprise! There was a grenade in there! After the explosion, head inside the room and to the cupboard on your right to find sulfur ointment, Laudanum, and a sheet with a warning about the medicine (an important one at that.)
Then, head back to the hallway where you came from. Now, you’re going to boil the sulfur you found. Go back into the room you got the charcoal from and put it on top of the hot plate by the door leading into the main area. Use a match to light it then boil.
Now, all you need is saltpeter. Which, unfortunately, means you have to go back to the Quartermaster’s Stores in the building you were just in. Head outside and go through the alley again, then back in through that door you ran out of.
Thankfully, you can make this trip quick. Turn left to head back up the stairs and into the hallway where the monster was before. Go straight back, grab the saltpeter on the shelf, and head right back out.
Go back to the arsenal, combine all your ingredients, add it to the machine, pull the lever, and you’re all set. Head back out to the tank, put in the bullet, and fire away at the gate.
