SKY SHARK IN BOX NINTENDO NES

Sky Shark is a top-down shooter similar to Raiden. You start with four lives and three bombs. With this (you can get more lives at certain point intervals, and more bombs can be found), you, the "Sky Shark" of your squadron, traverse five levels of enemy-infested battlefields with up to six weapon upgrades (apart from bombs and gun upgrade, there are no other weapons to be found). Includes three difficulty levels and support for two players.
