Welcome
Learn about the current situation at JCR Outpost




The first objective

• Find the key to the garage.

Names are random each playthrough so what you need to do is talk to all people at the outpost until you find the key.

Places that are locked during this part (so don't bother going there as it will just consume your stats) are: Storage closet, reactor, waste closet.

You can go to the jail during this part. If someone is using the toilet talk to them to earn an achievement. If no one is there you can simply select "wait for a while" until someone comes and uses the toilet.

Floater
Talk to someone while they're doing their business

• Walk around the outpost and try to find the person with the key.
  
• During this step you are safe, so don't bother grabbing a gun or a knife if you see them.
  
• Bear in mind that if someone is standing near a door you cannot use it, so select "wait for a while" if that happens.
  
• Maintaining your stats is not very important, so don't worry about it too much, when your stats reach 0 you simply respawn in the jail with stats fully restored and important items collected such as keys remain in your inventory. Collapsing will also earn you an achievement.

Deadbeat
Pass out from not taking care of yourself

Probably the easiest method of finding the key if you wanna go fast is simply going to any of the halls, and selecting "wait for a while" and waiting for new people to visit the room, then just talk to each new person until finding the garage key.

• After getting the key; head to the garage and pick up the dynamite.
  
• From the garage follow this path:
  
  • Move to the back of the buildings.
    
  • Move to the side of the building.
    
  • Move to the front of the building.
    
  • Move to the parking area.
    
  • Drive to the ice sheet.
    
  • Investigate ice crack.

Occurrence
Take science too far




The second objective

• Find the 3 keys.

Your first focus should be finding the 3 keys:

1. Red = Garage key
   
2. Green = Reactor key
   
3. Blue = Janitor key

It's recommended to backup your save at this point, as when you die you have to restart the game from scratch.
Back up your game periodically as you complete more steps.
Quitting from the game is not required, just alt-tab from it copy the files somewhere.
Save location: C:\Users\Your user\AppData\Roaming\Occurrence

• After the event we wake up at the jail.
  
• From now on crew members will begin to die, and a random crew member will be a monster.
  
• Be sure to grab a gun after leaving the jail to protect yourself.

The best way I found to finish this step is simply going to the office, grabbing a gun and selecting "wait for a while" until crew members enter the room, then talking to them and grabbing the keys. If you're lucky you may even get all 3 keys at once.
If the crew member turns into a monster select "approach the creature" to stun it.
Now you know who from the members is a monster and who to avoid as you explore the area.
Grab another gun after that; leaving the room and checking where other members are located using the pause menu.
The crew member that is a monster will only turn after you perform an action while said member is in the room with you, so the easiest way to avoid the monster is keep moving from room to room.

Using any weapon to stun the monster earns an achievement:
Resourceful
Use an item to defend yourself

• If you got the key to the reactor head inside and overload it.
  
• If you got janitor key you can access the waste closet and the storage closet.

Note: You will be defenseless and die if the monster will enter the computer room while you preform actions, so open the pause menu and check where members are, and pick up either a knife from the kitchen or a gun from the office after checking the tape just in case.

• Inside the storage closet pick up the program tape.
  
• Go to the computer room and check program slot.
  
• Use console and use the radio to translate the signal.

Hardware
Decypher the hidden message

• Now you need to go to the garage and grab the dynamite again.
  
• Head to either the waste closet or the storage closet and descent the ladder.
  
• Keep moving and reach the reactor base.
  
• Investigate ice crack
  
• Climb down the hole
  
• Now solve the puzzle, the solution should be in the pause menu if you deciphered the code using the radio.
  
• Simply touch the symbols in the order shown in the pause menu.

Gateway
Open the gate


Now follow these steps:

• Move to the core of the ruins.
  
• Move to the east gallery.
  
• Move to the east conduit.
  
• Remove a gem.
  
• Move to the east gallery.
  
• Move to the core of the ruins.
  
• Touch the heart of the ruins.

Closure
Survive the Occurrence at JCR Outpost


Now if you didn't get killed by the monster you will be missing one achievement.
So after the ending press continue, and find the last crew member (who is the monster) using the map, and simply let him kill you.
