Fort Solis is a new Single-Player Adventure Horror game that will allow players to experience the exploration of a mysterious fort on Mars.

In this guide, we’ll be covering the 1st chapter of Fort Solis.
Fort Solis – Chapter 1: Dark Descent – Walkthrough
Chapter 1 begins as players complete the tutorial of the game and reach the Solis Facility. Players will have to climb up by completing the QTEs which will start Chapter 1: Dark Descent. As the chapter begins, the first objective is to reach Atrium. Go straight towards the door in front and interact with the door to open it. Interact with the doors inside to unlock them to reach inside Atrium. A brief cutscene will play and after the cutscene, go to the Conference Room door in front and you will require an i5 Unit to manually open the door.
Go upstairs and you will find an i5 Unit on top of the box. Grab the i5 Unit and go down the stairs. Interact with the Fort Solis Map Data outside of the Stairwell/Elevator door to download the Fort Solis Schematics. You will get access to the map of Fort Solis and will be able to use the map to see the locations. Now, go to the Conference Room door and place the i5 Unit to open the door.

Make your way to Room No. 2: Mining+Site Development and look at the calendar to get the code for the Computer Terminal in the room. The code will be 0807 and you need to enter the code by interacting with the Computer Terminal. After entering the code, you will get access to the computer terminal and you will have to unlock the doors. Switch the Tab to Surveillance and unlock the closed doors. Now, go out of the conference room and interact with the Stairwell/Elevator door to open it.
Go down the stairs and enter the Crew Quarters. There will be two rooms in the Crew Quarters, Rec Rooms and Private Rooms. The Private Rooms will be closed so, you have to go to the Rec Room and then go to Canteen. From there, you need to keep walking in the Hallway until you make your way around to a closed door which you will get to open by Overriding. Opening the door by overriding will get you to the Private Rooms.
Make your way to Helen’s room to access her Computer Terminal to see videos of her work progress. After that, make your way toward the Crew Quarters and go inside Claire Smith’s room. The door of the room will not be fully closed so as you go near it and interact with the console, it will open. Go inside the room and pick up the Level 1 Access Card which will give you access to all the doors that requires Level 1 access in Fort Solis.

Exit the room and go ahead in the hallway to find Dawson Robert’s room which will require Level 1 Access. Go inside the room to find another i5 Unit which you will need later in the chapter. After grabbing the i5 Unit from Dawson Robert’s room, exit the Private Rooms and go to the Stairwell to go down further to reach the Medical Bay. As you open the first door of the Medical Bay, you will find that the next door of the Medical Bay has been sabotaged.
Use the i5 unit you found in Dawson Robert’s room and override the door to open it. Now, explore Medbay and go to the B2 Subsection. You can go to all of the rooms inside the Subsection to find various clues. Go to Room No. 3 to find a Computer Terminal. Access the Computer Terminal and select the Surveillance tab to open the Medbay door. Exit the door and go back to Medbay Lounge to enter the closed door.
As you enter the surgery room, inspect the dead body. Move around the camera and interact with the body to gather clues. After inspecting the body, you will pick up the Level 2 Access Card. Go out to Medbay Lounge to see a person and it will start a cutscene. After the cutscene, go through the tunnels to come out of the Stairwell.

Go up the stairs to reach the Atrium and go through the cutscene to conclude the first chapter of the game.
