For this achievement you must score 1 million points in OutRun mode. To get this very easy, take the root Left, Left, Left, Right, so the last stage is Legend. Make sure to follow the tips and point chart above and to always pass rival cars after drafting them! This nets you 50,000 points every time. Also, having the difficulty between very easy and normal comes down to personal preference. You don’t get as much points playing on very easy as you would on normal, but if you know what you’re doing you should have no problem getting this achievement. I average 1.1 million to 1.4 million every time I run this on very easy.
I hope this solution helped! Leave a comment letting me know if there is any room for improvement! Thanks.
