Quantum Conundrum, released yesterday for the PC, now has a specific date for the Xbox 360 and PlayStation 3. PlayStation Network gets the puzzler on July 10, Xbox Live subscribers may buy it on July 11.
The game does not yet have a price on either console service but as it ran $US15 on PC, that sounds like 1200 Microsoft Points/$US14.99 to me.
Quantum Conundrum is a first-person puzzle game, and if that makes you think of Portal, it should. Kim Swift, the project lead on Portal is this game's designer. Jason Schreier reviewed the game for Kotaku' on PC and really enjoyed his time with it.
