Infinite Suitcases
In some areas throughout the game, there are places where various things you destroy to find suitcases regenerate, so you can shoot them again. Take advantage of these to give all your fighters maximum power-ups. The best places to do this are the areas with pipes in your way (near the end of area 3 and in the sewers of area 5).
