Okay something someone said before, flying to the village I saw a tunnel all lit up with a bridge to it. Inside is a door with a keypad that has a red light on. Shooting the keypad gives off sparks (Normal keypads don't do this) also, running into the door your players head glitches into it like it would open up. You can also sprint into it like you can on locked mission doors.
Has anyone tried shooting a stun gun at the keypad?
Maybe the 'egg' is where the passcode to this door is?
The glyphs with numbers are important. What is found when they're all put in order?
