This game operates 100% and has been 100% reliable have never had an issue with it ever. I bought this and a twilight zone from a collector in Cincinnati about 2 years ago who was very particular and had been through the entire machine. Their are a lot of mods on it , to many to list so look at the pictures. An excellent condition playfield and cabinet art. The back box has a few small dings on edge . Overall you will rarely see one in this kind of excellent shape. I am looking to change up my collection and can assist with shipping if needed.
