That premium PlayStation Plus subscription is about to get even more hard to resist. Joining the ever-expanding list of subscriber perks is Airtight Games' well received puzzler Quantum Conundrum. After tomorrow's PlayStation Store update, Plus subscribers will be able to download the game absolutely free. Quantum Conundrum will become one of many games that are available free to subscribers, though you will of course lose access to the games if you end your subscription.

I've heard nothing but good things about this game and I've been meaning to try it for quite a while. Perhaps it'll be the last push I need to actually buy a Plus subscription.
