Mega Zone is an early overhead Shooter from Konami
This game has flavors of several different video games rolled into one. It is
mostly like Xevious, being a shooter against a plethora of
enemies, each with a unique characteristic. Unlike Xevious, however, that only
allowed you to travel in one straight path, Mega Zone periodically allows you to
choose different paths. For most of the game, the player's ship flies along a
river. When the river forks, the player has the option of following either
fork.
The game also has elements of Scramble, in that the player fights
through numerous zones in the struggle to reach the end. Where Scramble has a
progress bar at the top, Mega Zone gives the player a map, and shows the player
the progress along the map between lives. The main enemies of Mega Zone are
giant robot eyeballs. Easily enough destroyed, they still pose a menace. Smaller
eyeballs leave teardrops when destroyed, which when picked up, give bonus points
and wipe out all enemies on the screen
