For the most part, the Xbox 360 version of Gauntlet is a faithful arcade port. When you play the arcade mode--which isn't much fun by yourself, honestly--you can keep hitting a button to add more health. It's the equivalent of dumping more quarters into an arcade cabinet. If you play using the default settings, your scores will automatically be compared against the worldwide leaderboards. The catch here is that the more times you give yourself a boost of health, the more you divide up your score, so the highest-ranking players are going to be the ones who get the farthest without squandering their health. The arcade mode features four-player support, but only if you're playing with some friends locally.
