Kill 1000 zombies once a day (sewer), and you can get the chance to use Cyclone AK47. You can use Cyclone AK47 under any Cataclysm map. Kia, the original weapon, will be replaced by cyclone AK. You don't need to buy it in the purchase menu. Note: You can only use Cyclone AK47 once. If you are T or have a reason to quit the game, Cyclone AK will disappear and become the initial weapon. Kia, if you want it again, please continue to kill 1000 zombies the next day.
