Looking to add more games to your Xbox library? The next run of Games With Gold freebies are now available on Xbox One and Xbox 360--and they've arrived a little early.

On Xbox One, Superhot--the FPS where time only advances when you move--is free. And on Xbox 360, the backwards-compatible puzzle game Quantum Conundrum from Portal designer Kim Swift drops to the low, low price of $0.00 (it's still showing as $10, but should become free any time now).
