I just had to register and respond to this one, after trying to figure out this code ever since I bought Universe Sandbox a few days ago on steam (I am a new player). I finally just a few moments ago figured it out, and boy did it surprise me how it was so complex at first but once I got it I was like "Oh yeah, I get it now." lol.
I have to admit that achievement had me stumped until I finally got it, I only wish more of them were as well thought out as that, cheers on that one Dan, also I am really enjoying the game and not regretting my purchase one bit; this was the best $10.00 Dollars I have ever spent.
P.S: I am free to help anyone with the achievement aswell when ever you can catch me online, just P.M me either here or through steam (SGElite23), know this though before sending me a message, I won't right out give the answer away because it kills the point of the achievement, just so you know before you write thinking I will give the answer and then I don't.
