Click the Pump action reload to reload, and click the gun to fire. please don't spam click the pump. it WILL break. Also, The mechanic for only being able to shoot it when reloaded is from @Bronze_Knight Credit to him! However I had to change the bullet sprite (It was literally a bullet, not a shotgun shell).
This was created using a random PNG of the default shotgun from TF2, and also took about 2 hours to make. sounds are from TF2, so it pretty accurate. I hope this doesn't get taken down.
