• Two Players A: A split-screen two player mode
• Two Players B: A co-op two player mode

[edit] Difficulty settings

• Easy: All projectiles, beams, and flames will move slowly. Every enemy and boss is relatively easy to defeat; and almost all enemies will just walk across the screen hardly firing at you.
• Normal: All projectiles, beams, and flames will move somewhat faster than they did on easy; every enemy and boss will fire at you more often. Boss take more shots to defeat and some will have extra attacks. New enemies will appear.
• Hard: All projectiles, beams, and flames will move a lot faster than they did on normal; every enemy and boss will fire at you more often and more accurately; enemies will reappear quicker. Bosses are a lot tougher to defeat may have extra attacks. There is an additional boss at the end of the game as well as a different ending.
