The Chains of Judecca are massive chains located within the Inferno, all created to keep Lucifer imprisoned in Lake Cocytus. All of the Chains that Dante encountered are found each time that he descended into a lower circle.
The Chains of Judecca are enormous lines of chains with a central, elaborate structure, possibly a lock. Being breakable, this structure will develop a bright sheen as Dante came near it. These chains are embedded in the walls of almost every Circle of Hell and all led down into the Circle of Treachery.
Every time that Dante found one of these, he used the Scythe to destroy it to continue his progress. However, each time that a chain was broken, Lucifer's laugh was heard, indicating that he was slowly being freed.
The last chain was found after the last Beatrice Statue, right before Lake Cocytus. Breaking this one led 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 was unique to the game.
- These chains are apparently named after and led 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 mentioned during the last battle with Dante that he tried using others to break the Chains of Judecca and free him in the past. Among those that he named are Ulysses, Attila the Hun, Alexander the Great and Lancelot. Only Dante succeeded.
