Evil doers, feel my wrath!
― Murray, before starting the mission
Murray had to use his mighty strength to sabotage three alarm horns around Dimitri's nightclub.
The three alarm horns would tip off Dimitri during the gang's heist. Murray was the only one who could destroy them. To do that, he had to use his stomp move to pick up objects (or guards) and throw them at the sirens.
Behind the scenes
This was one of the jobs featured in the Sly 2 E3 demo and the demo included in the PlayStation 2 release of Ratchet & Clank: Up Your Arsenal.
