All you have to do is download the After Burner Climax demo between today and May 9 (Japan time) to enter. 500 demo-ers will receive 200 Microsoft Points just for trying home conversion. 500 people that buy the game get 800 Microsoft Points, which is like getting their money back. After Burner Climax only costs 800 Microsoft Points.
Unfortunately, this promotion has not been announced for North America so we’re not sure if entries from other countries are valid or not.
