Steel Empire

Description
Steel Empire is a side-scrolling shooting game for the Sega Genesis video game system. The player can choose to fly the Striker Plane or the ZEP-01 Airship to combat enemy fighters through seven progressively harder levels, each containing a boss character at the end, which must be defeated in order to advance to the next level. Many of the levels also feature less powerful mini-bosses, which appear about halfway through a level.

Story
The year is A.D. 18XX, the age of steel. The MotorHead Empire, a militaristic nation led by Dictator Sauron, has conquered and enslaved most of the world. The Republic of SilverHead is the last hope for the world.
