You gain experience and cash by fighting other players. Each fight takes away some of your health too. You must have at least 16 health and 1 energy point to engage in fight. The outcome of a fight depends on your Mob Size and the kind of equipment that they have. In a fight, whether attacking or defending, the game automatically equips each mob member with each a best weapon, armor, vehicle and special items that you have. Each mob gets 1 weapon, 1 armor, 1 vehicle and 1 special. If you have Mercenaries, they will enhance your power by taking extra 1 weapon, 1 armor, 1 vehicle and 1 specials to the fight. The maximum mob that can be used in an attack is (your level) * 5).
