I found the source code containing all kinds of spoilers, cheat codes etc etc... im not gonna give you the 11 cheat codes haha but ill give you some of the game messages, that you get throughout the game by digging down.

1.-Good! You know how to drill. Now get as many minerals as you can and fly or drive to the base. The base is on the surface at the far right. Watch your fuel gauge. Unless you buy more fuel at the base you will probably run out of fuel before any other dangerous events occur. While you're inside the base, sell all minerals and try to upgrade your fuel tank. The first upgrade is only $200 Don't forget to fix your drill and refuel
Good luck!

2.-Some minerals glow. They are radioactive, so be careful while mining them. They are relatively valuable, but can quickly raise your radiation level. If the level rises too much,it's harmful to you. If you plan to mine many radioactive minerals,then you will need to upgrade your Bio-X.

3.-The deeper you go, the more valuable minerals you find. Watch for silver and gold. They are 250$ and 750$ respectively.

4.-The granite is harder than earth by about 100 times. It can really damage your drill if not careful. A stick of dynamite can easily take care of it.

5.-Getting hot, don't you think? You haven't been neglecting your radiator, have you? If you have, you need to upgrade it. Otherwise, you won't be able to go any deeper. If you already done so, too bad! It was using your fuel for no purpose.

6.-You have probably noticed that the base has Coal Burner and Petroleum Refinery upgrades. Coal and Petroleum can be used to charge the battery when proper gadget is installed. When the battery is charged, the fuel is no longer used. This can be helpfull when you have a small fuel tank.

7.-There are a lot of gems further down. They are more valuable than precious metals, they weigh little, and they are not radioactive. You will also see marble rocks. Marble is much harder than granite. I would advise you not to drill through it unless you have a very powerful drill and a lot of drill fixes. Dynamite won't affect marble, but TNT explosives are effective.

8.-There is a lot of lava below you, so be careful. You'll probably have to drill through it to get some precious minerals, so you'll need to upgrade your hull. Also, don't try to handle lava if you have a weak radiator. In addition, there are many gas pockets. They are hard to detect and can cause explosions. A Natural Gas Burner can be used to convert them to energy. The N. G. Burner sucks up the gas and prevents explosions. Furthermore, you'll find new, extremely radioactive minerals below 6000 ft. These valuable minerals are Thorium, Uranium, and Plutonium. They are powerful sources of alternative fuel that you can use if you install a nuclear reactor in your ship.

The rest of the messages you are gonna have to find out by yourself.

awwwwwwwwwwwwwwwwwwwwwwwwwwww took me soo longgg...

Sorry. Company's policy of nondisclosure.

WTF, i dont get this.
"All game messages if you missed'em"
"The rest you have to find out yourself"

Chill, I removed the rest of the messages. You should be able to find the on your own (while playing).

Okay, i just saw the ''edited by alexxz4

The source code (for MLU1) is actually publicly available; you have to find it for yourself though.

I found a message that said *******, *******, and ********* can not be bellow **,*** ft!
U gotta find the minerals and depth Urself!

td addict,,, ive been all the way across the screen at 30,000 ft and have not seen any messages. are they hidden in the minerals?

OK I'll give you 2 hint words: nuclear, reactor.
U get the message at ~13,000 ft

I know,

Thorium, uranium, and plutonium can not be found below 13,000 ft!

Exact message at 12,600 ft:

Quote :

Radioactive metals are no longer available because of the extremely high temperatures. You have only your fuel tank and gas pockets to rely on.

i got a message on around 17k, but there was alot of lava, so i had 2 close the message and fly to a safe place D=
