Choose everything that you want for your equipment, and do everything else based on the game type. When you choose "Hunt", press Black, choose the heaviest thing, and press A. Then, do this repeatedly. When you have taken out everything, put everything back. When you run, it takes it down much slower as if you have nothing.

When selecting your rifle in action zone, it is best to get an automatic. You will be able to shoot faster and will not get attacked as much.
