In Zombie Shooter Deluxe, you have to kill a lot of scary zombies before the game is over.
Multiple zombie targets will appear in front of you when you tell them to. You have to shoot at all of them. For each hit, you will get a certain number of points. To make a good shot, all you have to do is click on the mouse that has the zombie mouse on it. This will let you set the thing as your target and then fire a shot that hits it right where it needs to. Remember that there is a time limit for each goal.
Have fun and good luck!
