The objective of the game is to finish all the waves in each level by destroying all the monsters on the screen. By getting a better score in a level, you will receive more money. This money can be used in the shop. Inside of the shop you can select different costumes, weapons, special powers, and any different equipment you want to use. On higher difficulty modes, you will face different formations of stronger enemies. As a reward, you will receive more money. Try to beat the game on all difficulties, and get the best score possible to climb up on the ranking table. Don't forget there is also Survival mode that tests your skills to the max. Try to use different combinations of equipment to survive as long as possible.
Note, money received equals the difference between a levels' old highscore and new highscore (if a score was already set for said level).
