We’ve seen a lot of interesting discussions in the community on which order you want the weapons to appear in Gun Master mode – Now we are giving server admins the choice to decide between six different presets, each bringing a twist to this popular game mode in Close Quarters and Aftermath. The available weapon progressions are: Normal (default), Normal Reversed, Light Weight, Heavy Gear, Pistols Only, Snipers Heaven, US Arms Race, RU Arms Race and EU Arms Race.
