Conditions: A PC terminal with Advanced Targeting mod installed required;
Step 1: Enter the pyramid. There is a smiley face on the wall. 
Get closer to it, the face disappears and an illuminati eye appears outside the pyramid. 
You will find image of the tower of avalanche airport.
Step 2: Go to the avalanche airport and enter the tower. 
You will hear a voice, decode its SSTV signial, you will get an image contains boom25 and the kraken.
Step 3: Go to the kraken and hit it,
it will start moving heading Krakabloa, 
when reach the islands the kraken disappears. 
Sea level will drop and a panel with laser and code will show. 
After the first two lines of the character are converted into hexadecimal, the square is extracted and 0 = a, 1 = B is used to solve "SEVEN TIMES ONE NINE ONE", and the third and fourth lines are unknown
OUCH!!!! lol
@NewmanSTAR Then don’t you know the other two lines?
@BeastHunter yep)
Is this part of the mod?
@TheSolarFlare I really wanna hear what he would say or intro, like, "Ahh simpleplanes, a game where you make planes by placing blocks, adding wings, and making them fly. sounds simple enough right? then he goes on a tangent on how the community makes complex stuff that are not planes Simple planes isn't really a game where you can discover much lore when you look at it at the surface, Just a few islands with small airports and some military stuff here and there..."
Somebody call matpat, we need to solve the lore
nice found
This just feels like one big lead-up to a rickroll
This is the kind of in-game lore that really impresses me, the kind of stuff reminiscent of the Cicada-3301 Incident. I love it when developers and mod creators do this kind of stuff, it really adds an intriguing level of mystery to the game.
Interesting
@jamesPLANESii It's only half solved, and there are two more lines of characters, and I don't know how to find the answer.
Someone finally bothered to solve this lol
