Did you know? That the moon was used as a giant field long long ago for AI with giant nuclear blasting rockets? That's why the moo n has almost no atmosphere and Star Wars is a twisted version of this theory.
Here's how to get 3,000,000 feet. First u need tank and golden gun and the 2hour medal. Shoot at full speed aim for top right corner then use missile. shoot turtle once. let him bounce three times and shoot again. repeat process until run out of bullets. then hit with nukes (100) and reach 3,000,000. Note: took me long time.
