Portal dev's new game is Quantum Conundru

As promised, Portal co-creator Kim Swift - who now acts as creative director at Airtight Games - has revealed her new game and it looks awesome. It's a first-person puzzle adventure titled Quantum Conundrum.Playing as 'a kid', you explore the huge and bizarre house of your uncle - a wacky inventor named professor Fitz Quadwrangle - which looks more like a laboratory for his creations. An explosion in the house sends your uncle insane and your mission is to locate him and figure out what's going on.But getting through his intricate house is a huge puzzle, for which you'll need the IDS device - Inter-dimensional Shift device - on your arm. This lets you switch between dimensions with different physical properties. For example, you can switch to the 'Fluffy Dimension' in which everything turns plush, so heavy things are light which allows you to move objects that are otherwise too heavy. There's also a slow-mo dimension in which moving objects (except you) move 20 times slower. As you progress from one puzzle room to another you'll be able to switch between different dimensions to solve the puzzles, and sometimes combine different dimensions with truly clever results to reach the exit. Swift explains it all in the video below:So you use an arm-attached device to defy physics and reach the exit of a series of puzzle-filled laboratory rooms. Sound familiar? Regardless of its Portal similarities, Quantum Conundrum looks and sounds amazing and we can't wait to see more of it. Luckily there's not long to wait - it's out in 'early 2012' on Steam, Xbox Live Arcade and PlayStation Network for PS3. Mike Jackson
