After making it to the second floor on the first level, and breaking the metal door, head left to find the Hatch.

Listening to the hatch, you will hear the sequence:

引用自 Hatch：

]-.-. .... . -.-. -.- / .-. .- -.. .. ---

which translates to "Check Radio".

After doing that. complete the level like normal



It will play for a second, then switch to, you guessed it, morse code, which says

引用自 Radio：

].-.. . ..-. - / .-. .. --. .... - / .--- ..- -- .--. / .-.. . ..-. - / -.-. .-. --- ..- -.-.

which translates to "Left, Right, Jump, Left, Crouch".



Once at the Hatch again, stand in the yellow square and move like the radio told to. So press Left, then right, then jump, followed by another left, then crouch.

The handle on the hatch should start spinning, indicating that its opening.



Or so you thought.





Going down the ramp, you will be met with a locked door and a suspicious keypad needing an 8 digit code. That is 100,000,000 possible codes that it could be.



No.


Think back to when you first joined the game, you got something.

That's right, you got an achievement.

Hidden in the depths of the first achievement lies our answer. An eight digit code.




After all this time, all this effort. we have found the answer. Now all that's left is for you to see whats behind that door.

Thank you.
