The name of the game refers to your call sign, i.e. "Sky Shark" of a nondescript World War II squadron. Your goal: blast through five levels with as many as six gun upgrades. Although most levels look similar to each other, the end-level bosses are appropriately tough to kill, and good music and animations make the game a pleasant time waster. With three difficulty levels and two-player hot-seat support, Sky Shark is a well-rounded shooter that deserves not to fall through the cracks of time :) Recommended, although by no means a must-have.
