GS:Mercy is not part of Knack's vocabulary. He happily uppercuts a defeated enemy into a steaming lake of molten lava and flings an aircraft by its tail into the unforgiving ground. And don't believe for a second that he sheds a single tear for the pilot engulfed in the flaming wreckage; Knack doesn't let sentimentality distract him from a good fight. The only thing he desires more than brutal destruction is finding creative ways to exterminate his many foes. At least that's how the cutscenes play out. When you're given control, Knack mindlessly punches his way through corridor after corridor of enemies, and you're left wondering why Knack gets to have so much more fun than you do.
