E C L I P S E

You wake up on a blackout space station.
Stranded. Amnesiac. Alone. No one to rely on but yourself.
In front of you is a door, "protected" by some kind of loop that keep leading you back to the other end of the same corridor. Your objective: unveil the truth beyond that god forsaken door, no matter what it takes.
"What the hell am I going to do?" You probably ask yourself. That's right, you are not prepared. Not yet. This is when the space survival 101 kicks in.
1. Flashlight (and batteries)
This is, no doubt, your dearest friend throughout your little journey. This light source not only help you navigating your way in the dark but also shed light on hidden corners so that you won't miss a locker or a drawer. Also, flashlight's long lost little brothers, named Batteries, can be found on the station. They need each other. Remember to keep your batteries reserve in check. Wouldn't want to get lost in the dark, would you?
2. Stamina
You aren't athlete. Your job is (or rather, used to be) to sit in front of computer for hours, minding paperwork (just like me, probably). Sprinting for an extensive duration makes you exhausted. Rest and wait for your stamina to regain. Don't worry, it won't take long. Trust me, this is incredibly important. 
3. 6
4. Survive
You are no fighter, either. Within Thirty-Six Stratagems, retreat is always the most effective method. Whenever you encounter a threat, there are 3 things you can do: run, run and run. Don't fight UNLESS you are cornered. None of the threat here are grotesque though, don't be scared. This is when you need to save stamina. If you run out of it during a chase, God helps you. 
5. Items
Keep an eye out for items. They are, one way or another, keys for your progression, and in certain case, your survival. It might be quite a challenge to sight them in the dark, so careful observation is highly required. 
6. Perception
This is, no doubt, the most important factor. Memorizing routes, assessing situations, taking mental notes of any clues and hints that you happen to come across. No one can teach you to be perceptive beside yourself. 

Unveiling the truth behind that door is the goal, but that is not the only way. Sometimes, be a coward and keep moving backward might help too. It is not like there are anyone to judge you. Your choice. 

Now you are prepared. Good luck surviving!
