Major Stryker

This is a great EGA shooting game from Apogee, who were better known for their platform games like Keen and the original Duke Nukem series. However this game is also pretty well made. It features frantic graphics and SoundBlaster sounds/music. There are lots of ship powerups and lots of enemies to fight. The only problem is that sometimes there is so much going on that it's hard to keep track of what is an enemy and what's part of the background. (3D Realms (formerly known as Apogee) released the full version of this game as freeware.)
