.68 Caliber Paintball-Indoor, but Excalibur is much nicer and much more fun.
The fields are just awesome. I think theres about 8 different fields all of which are great. You also get a good variety of fields because theres speedball, hyperball, airball, and woods fields. It has a nice shop if you need to buy anything or get something fixed. The prices for entrance and fills are pretty cheap. The paint is kind of expensive and you have to use their paint but it is Diablo paint so your getting high quality paintballs. I like these fields so much id like to go just about every weekend. This field is the best in my area and probably one of the best in all of Michigan.
