The following are descriptions on the exact requirements needed to get onto each high score board.

Arcade: You must have the game difficulty setting on at least 4, and the match point setting on 2. Then, you have to defeat the last boss in Arcade Mode (Xion) under a certain time. 10 minutes is your goal if you want first place.

Arcade VS: Play Arcade Mode with the same settings as listed above. Then, have a friend break into your game to challenge you. The more times you cream your friend (or cheat and control the second player yourself), the better your high score on the board.

Survival: This one is the only mode you can tamper with the difficulty settings in and still get on the score board. Set difficulty at 1 and match point at 1 for a better chance at bigger kill counts.
