This is a brand new cheat and has been discovered only a several days ago so make sure to try it before it gets discovered by the Administrators. Today is June 1 2010 and its still working! This cheat causes your account to receive 15k uranium every time you send it! So make sure to use it fast before it is discovered. I made 500k uranium using this cheat and so far I'm a full elite Goliath!
