Mad Doctor: Shooter Game

In this shooter game, you control a mad doctor armed with a gun with infinite ammo and have to survive for as long as you can against endless number of enemies. These enemies will have different kinds of weapons and use various strategies to defeat you.
As you kill the enemies, they may drop power ups like special ammunitions (3 kinds) and health kit. Health kit will heal you for a certain amount when picked up and special ammunitions can be sued by switching you gun. These special bullets are very strong, but are limited, so use them wisely! As you can guess, you will lose the game when you run out of health.
So, let’s see how long you can survive!
