You somehow sneaked into the SCP foundation, you were very careful... but you actually didn't meant to sneak in, it was by an accident.

You walked in the hallways, you see It's a bit pretty dark, but you could still see, the wall had the red line, meaning you managed to get into the level O5 chambers...

Until... you hear someone. ... almost behind you.

Xiyz: "Hey you sneaky link, stop right there. How did you get in here?"
