The Chains of Judecca are massive chains located within the Inferno, all created to keep Lucifer imprisoned in Lake Cocytus. All the Chains that Dante encounters are found each time he descends into a lower circle.
The Chains of Judecca are enormous lines of chain with a central, elaborate structure, possibly a lock. Being breakable, this structure will develop a bright sheen as Dante comes near it. These chains are embedded in the walls of almost every Circle of Hell, and all lead down into the final Circle of Treachery.
Every time Dante finds one of these, he uses the Scythe to destroy it to continue his progress. However, each time a chain is broken, Lucifer's laugh is heard, indicating that he is slowly being freed.
The last chain is found after the last Beatrice Statue, right before Lake Cocytus. Breaking this one leads to the fight with Lucifer himself.
- The Chains of Judecca are not present in the original Inferno; the subplot of Lucifer attempting to free himself from Hell is unique to the game.
- These chains are apparently named after, and lead into, the deepest part of Hell, named "Judecca" after Judas Iscariot. Here are found the ones who betrayed lords, masters, benefactors and God, in the ninth and final circle.
- Lucifer mentions during the last battle with Dante that he had tried using others to break the Chains of Judecca and free him in the past. Among those he names are Ulysses, Attila the Hun, Alexander the Great, and Lancelot. Only Dante had succeeded.
