I used to play at this one paintball field that was indoors. it was one barrel field and the floor was covered with sand, so it was pretty difficult to move. FCP is a great place to play, plenty of open space to run fast
You can bring youre own paint, the field fee and air prices are reasonable, the fields are pretty good, ive always had fun at this place. there arent really any complaints, just remember to bring some mosqito repellent with you as there is a tendency to get eaten alive. speedball is probably their bigger field; its shaded under some big oak trees so its the place to play when the sun is beating down on you. the hyperball field is much smaller, and the bunkers smaller as well, so you can expect quick action and little cover. the barrel field is much more open, medium sized, and a good place for beginners to learn the basics of the game; however, i suggest for the bigger people to head for the bunkers with the most barrels since the smaller bunkers tend to offer very little cover.
i have yet to try out the forest type fields but i hear that besides the bugs, they can be very fun. i recommend this field to anyone wanting to play and is in the area.
