If I could only make one game recommendation for Mac users, at the moment it would have to be BioShock Infinite. The game received amazing reviews from critics on the consoles and our friends at Aspyr quickly followed up with a flawless Mac version back in August. If you’ve yet to pick up a copy, you now officially have no excuse: GameAgent and 9to5Toys are offering BioShock Infinite for Mac for 75% off from now until Sunday.

That means you’ll get BioShock Infinite for $10 instead of the usual $40, and we’re also throwing in the $4.99 Columbia’s Finest DLC for free. Best price on Amazon: $31

On top of that, GameAgent is giving away some crazy prizes to celebrate its brand new site redesign. The new site has a “Mac Match” feature that lets you setup profiles for your Macs to easily find supported content, and also a new Wish List feature to get automatic deal alerts when games you’re interested in go on sale.

Go create an account on GameAgent.com and make sure to put a name and legit email when completing the contest entry page to win a fully loaded 27-inch iMac with a 3.4GHz Quad-core Intel Core i5, 16GB of RAM, 1TB drive, and NVIDIA GeForce GTX 780M 4GB GDDR5 graphics. It will also come loaded with every BioShock, COD, Duke Nukem, Quake 4, Civilization and Star Wars title GameAgent sells, along with a long list of other titles and DLC, and there are many other prizes too. Full details of the contest rules can be read here (contest rules).

To get your 75% off BioShock Infinite, click here and enter promo code “9to5Mac” at checkout. Deal expires 11:59pm CST, Sunday, November 17 . Note: BioShock Infinite through GameAgent is the Mac version of the game and authenticates on Steam.

GameAgent also announced the release of the BioShock Burial at Sea- Episode 1 DLC yesterday with a same day release as the PC title.

Update: GameAgent ran into some “inventory issues” because so many of you are trying to take advantage of this awesome deal. Everything is sorted now and the deal is still live, but if you ran into issues, GameAgent will sort you out:

Update 2: The deal site PC gamer spambots have officially ruined the fun for everyone. GameAgent had to shut the deal down due to a high amount of fraud from bots eating up all the inventory on the deal code. We’re working with GameAgent to bring the deal back. Stay tuned.
