If you shoot an enemy when the warning reticule is on him but before he's launched his projectile you will receive a bonus.

It is sometimes possible to shoot chickens to continue your combo to the next screen.

Use the Bazooka as it is obtained during the first level. Its area-of-effect damage makes it much more forgiving than the other guns. Start the first level and use the revolver, because it hits the target instantly. Take it slow and kill every enemy with a single shot to the head.

Mayor is going to save his girlfriend from Mr. President. Mayor fights armys of ninjas, secret agents, and mummys. He also fights bosses too.
