Cycling Weapons was a challenge in the holovision show Annihilation Nation. It was the first of the cycling weapon challenges. It consisted of 8 rounds in the first playthrough, but 16 on the second. In this challenge, Ratchet's gun would constantly change after a certain amount of ammo was used. Weapons with infinite ammo or non-combative weapons, such as the Shield Charger and Qwack-O-Ray did not appear in these challenges. The wrench was also unusable. Ammo used during the rounds was not deducted from Ratchet's ammo total.
