Last Defense

Oh no, we are at war and the enemy is attacking us using long range missiles. Since we don't have long range missiles ourselves, we cannot strike them back and can only defend our population center from their attacks. Fortunately, we did build a very good counter-missile explosive gun. Unfortunately, we have only finished one so far, therefore that one will have to do against all incoming missiles. Well, one gun must be controlled by one person and we have decided that person is you! This is a very sophisticated gun so you don't have to worry about rotation, angle, etc. All you have to do is use your mouse to point at where the gun should shoot to and press the space bar to commence shooting. The gun will then shoot a special explosive which will be detonated at the target spot. Any missile head within the range of the explosion will be disabled. This explosive is very unique in that it will damage only missile, not buildings or people and therefore you need not worry about shooting near the population centers if necessary. There are 8 population centers and you should try to protect them all. Keep in mind that even though the gun can shoot pretty fast, its ammo is limited and we can only reload it in between waves so don't waste the ammo and since these are fast moving missiles, don't shoot where they are but instead shoot at where you think they will be
