Ratchet: Deadlocked, known as Ratchet: Gladiator in the PAL region and Ratchet & Clank 4th in Japan, is a Ratchet & Clank video game. The game was released for the PlayStation 2 in 2005. It was later released on the PlayStation Network as a remasterd HD version for PlayStation 3.
The story begins with Ratchet, Clank, and Al all being abducted by drones of an illegal combat sport called "DreadZone". DreadZone is a violent game show where heroes are forced to kill each other for their freedom. The three are given Deadlock Collars, which will explode if they are uncooperative.
As Dreadzone goes on, Ratchet defeats its most successful gladiators, known as Exterminators. As such, Ratchet becomes the most popular contestant. Gleeman Vox, the man behind DreadZone offers to let Ratchet become 'The Captain of the Exterminators'. However, Ratchet refuses, infuriating Vox. Ratchet is then sent to the Gauntlet of Doom, a supposed unbeatable course. After completing it, Ratchet returns to DreadZone's containment area, where Clank has figured out how to free the other heroes. In order to do so, Ratchet travels to the control level of DreadZone Station, intending to destroy the central computer.
Upon arriving there, Ratchet finds out that Vox has wired the station to explode. If Ratchet can't deactivate the explosives, everyone will die. Going through a massive gauntlet, Ratchet deactivates the containment fields and frees the escape shuttles. After a final battle with Vox, he reactivates the self-destruct sequence, planning on taking Ratchet down with him.
However, a shuttle that is being piloted by Al rescues Ratchet. On board, Clank removes Ratchet's collar. DreadZone explodes afterwards, leaving nothing but Vox's robotic arm behind. After the credits, Dr. Nefarious and Lawrence appear, still trapped on the asteroid. Dr. Nefarious gets angry since DreadZone is destroyed and he short-circuits.
The game received mostly positive reviews from critics. Although most critics were not happy about the removal of Clank as a playable character. The best rating the game got was 8.8/10 (GameZone and IGN) 4.5/5 stars (GamePro), and B+ (1UP).
