Both Ratchet and Clank are playable, though certain critics and fans have voiced their concerns regarding the game having lost its original edge and tone, as well as neglecting key character developments due to the story being under-developed. During the events of Up Your Arsenal , she is in charge of coordinating the Galactic Rangers to combat the growing threat of Dr. Clank is able to use stealth to sneak through many levels without engaging in combat, and can perform stealth take downs by sneaking behind enemies and completing a quick rhythm minigame to kill an enemy, gaining a bolt bonus for doing so. Deadlocked deviates from the previous installments of the series by reducing the platforming and puzzle elements, and focusing on the combat aspects with a predominantly arena-combat-oriented setting. After a number of encounters with the pirates introduced in Tools of Destruction , they finally manage to activate a device called the Obsidian Eye that allows communication with the Zoni. The real Plumber later contacts Ratchet, Clank and Qwark for assistance since he is stuck on a planet. PSP 85  PS2 62 .
