Mega Zone (Interlogic + Kosuka) - MAME - Shoot 'em up

This game has flavors of several different video games rolled into one. It is mostly like Xevious, being an overhead 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.
