Extra Credits
Ever wonder why they put "Deep Scan" game on Die Hard, it's so you can earn credits. For every 200 points you earn, you get a credit, on top of that, you can play over and over again and your credits keep adding up. This makes the game extremely easy, and at the end of a two player game, you get to use the rest of your credits to fight each other.
Hardcore Mode
At the main menu, highlight DIE HARD ARCADE, then press and hold X + Y + Z + B. If you did it right you'll have 4 credits and the enemies will be a little harder to defeat.
