Look at the next few pics at the bottom to see my AK-47 walmart shotgun mod =P it's so cool.
Step 1: Get your suit
What you should take to the battle ground:
a main gun
a secondary or backup gun like a pistol
camo, snow camo, or regular street clothes
2 or more magazines for each gun
a paintball mask or regular saftey goggles
500 or more BBs (depending on the game length and how many people are playing)
a backpack or something to hold your gear in.
If you are a sniper, take the stuff that I have listed below
what i take:
Step 2: Find a spot
If you are in a place where there are either no forest nor open space, use plywood to make walls skids or pallets work too.
To make the walls just simply lean the plywood against something and drill a hole in it big enough to see and shoot from.
