Zillion II: The Tri Formation is an action-shooting game for the Sega Mark III, released by Sega on December 13, 1987. I purchased this item approximately 30-40 years ago and stored it unused in a dark place. I opened it for the purpose of taking these photos. There is some deterioration due to age, but I believe the condition is quite good. Please feel free to comment if you would like additional photos, to purchase multiple items, or to request a discount. Shipping via Yu-Pack will cost around 1400 yen to the Kanto region, so purchasing multiple items is a good deal.
