Turrets are guns you can equip onto your ship. There are 6 types of turrets: Laser, beam, blaster, missile, torpedo and cannon. There are also 5 kinds of rarity: (From worst to best) Common, uncommon, rare, epic and legendary. For rarities from uncommon to legendary there are boosts to your ship for example more exp, critical hit chance, more gold/antimatter ect. Uncommon or rare gives you one boost, epic gives you two, and legendary gives you five.
