Steigar

Steigar is a scrolling horizontal shoot-em-up viewed from the side as you start out on an aircraft carrier and fly over various assigned missions while shooting and killing many waves of enemies including helicopters, planes, boats and tanks that come at you as you move from the left to the right. Complete the mission and it's onto the next one but touch an enemy or its weapon and you lose one of five lives. You have a standard cannon but power-ups can be collected from shooting certain enemies. Also to help you are limited smart-bombs that kill all on the screen.
