Rats - They come from the factories. If a rat touches you, your health goes down. After three touches, you lose a life.
-Small Rat - They only appear after you shoot a large rat. They are the fastest of the rats.
-Medium Rat - They are the most common. They are the second fastest of the rats.
-Large Rat - If you shoot a large rat, they will produce three small rats. They are the slowest of the rats.
Tank - This is what you move around the maze in.
Traps - If a rat or rats run into a trap, you get ten times the points as opposed to shooting them. Also large rats that run into a trap cannot release smaller rats. Running over a trap will not hurt you in your tank.
