Inferno crates were special crates in Ratchet & Clank: Up Your Arsenal. They cannot be opened with weapon-fire and must be hit with the wrench. They are orange with a black rim and adorned with the symbol of a red flame with a darker red silhouette of Ratchet in the middle.
When smashed, Ratchet enters Inferno Mode.
Although Inferno crates are most commonly found at Annihilation Nation, they can be found on other planets.
- The Inferno crate can be opened by using the Charge Boots to fly through it while the Wrench is equipped.
