Paintballing is now my new favorite past time. There is nothing more satisfying than hearing the yelp as you plant a perfect sniper shot on one of your colleagues backsides!
Bedlam paintball was a great laugh, and something I'd certainly do again. There are different games from skirmish and capture the flag, to everyman for himself or last man standing. No matter what game, if you've got to get rid of 600 paintballs its fairly likely you'll get trigger happy!
I'd recommend Bedlam Paintball for a group of 12 or more, but just be patient with the guns as the paint can clog them!
