Always:
Always make sure your kit works! You're dead without a gun.
Always Pack double the number of batteries you will need
Always bring your own bloody alen keys
Always bring a spare gun to field
Always Keep your gun up, or you'll miss an opportunity
Always bring loads of drinking water and tissue
Always talk to your team mates, call their name out to get their attention
Always listen when Pro players try to give you advice, be humble, learn the secrets and become great
Always give maximus respect to the field owner where you train
Always train any chance you get
NEVER try to shoot your gun one handed on the run to your bunker (you'll look like a proper tw@t)
NEVER shoot over your team mates backs if you can help it
NEVER assume that your angel is fully charged, check it you great big apes!
NEVER Lower your gun, Dynasty don't stop pointing their guns at the enemy, and neither should the rest of us.
NEVER assume that a mugger will stop after you shoot him the first time. If he keeps his gun up and keeps running, keep shooting.
NEVER do a dead mans walk, it just proves you got no game
NEVER leave your kit unattended, there's theives everywhere!
NEVER shout so loud that your team mates can no longer understand you
NEVER underestimate anybody, even if they only have tippmans of spyders, one of em will get you if you don't respect them!
