The Doctor

Lucas

Ryder

Viktor

Katrina

We here at IGN have seen and played Knack several times now, so feel free to reach our previews from E3 2013 and Gamescom 2013 . But today, we wanted to give you a glimpse into the cast of the game (apart from Knack himself, of course), complete with fresh screenshots and bios straight from the creators.If you want to see higher-res versions of all of the screens below, you can: simply click here “The Doctor is a successful inventor – his creations include anything from hovercars and airplanes to his masterpiece, Knack. The Doctor’s intelligence is matched only by his inability to think things through, which frequently results in trouble for himself and others.”“Lucas is the Doctor's 15 year-old assistant. He lost his parents at a very early age, and since then the Doctor has been looking after him. Lucas is smart, competent and hardworking – and is completely failing to get any respect from the Doctor.”“Ryder is Lucas’s uncle and is an explorer of sorts, there are few places he hasn’t been in his long treks through the wilderness. Ryder is strong, brave, and also not so good with the ladies, having spent perhaps a bit too much time alone.”“Viktor is a billionaire industrialist who made his fortune through security robots and other more military devices. He is also the hereditary head of an old family – complete with castle in the country – and is therefore rather formal in speech and dress.”“Katrina is the head of Viktor’s security forces, and dedicated to a fault. Katrina is extremely well mannered, which combined with her beauty, brains and athleticism makes for a devastating package – at least as far as Ryder is concerned.”Knack comes out on November 15th in North America and November 29th in Europe. Keep an eye out for our review in the coming weeks.
