Multiple shots + damage is all you need starting out. Just fly to one side or the other continously and you will rarely get hit ever. Zero challenge and no real "end" to the game.
Way too hard. Is this a joke? Lots of the games interface is copied from another Tower Defense game thats been out for awhile, i cant recall the name at the moment.
Dont usually care for these sniper games. There are quite a few of them out. However, the storyline, music, and quality put into this one made it very enjoyable. 4/5
