I play all the time. I just got a bunch more bruises yesterday. The cost depends on what kind of gun you want. my gun cost like 150$ and i also have a new barrel that cost $120. So for me it cost quite a bit but youy can get a cheaper gun. You can buy kits that come with mask and co2 and the gun which really is all you need. I wear camo pants and a sweatshirt and my mask and that is it when it is warm. When i play in the cold it sucks cause the co2 can freeze. Yesterday i shot one of my friends on the top of the head and he said it really hurt bad but almost everytime u get hit it hurts.
