The game - Zillion II - The Tri Formation - Sega Master System | SMS

There are only 8 levels in this game. At levels 1, 3, 5 and 7 you travel either on a motorbike or something else called an armorator. At levels 2,4,6 and 8 you run on your own. By the way, you can save Apple and Champ from the first part (these are also white knights). Then they can be asked for help on any of the levels of riding on a motorbike or on an armorator (you just need to press the A or B button on the second controller). The game is fun.
