Prince of Persia: The Sands of Time is free on PC

One free game every month as Ubisoft celebrates its 30th birthday.

Here's something that slipped past us during the tidal wave of E3 announcements: In celebration of Ubisoft's 30th anniversary, the publisher will be giving away one free game a month for the rest of the year.

This is a part of its new Ubisoft Club promo. It will work similar to Xbox's Games for Gold, where they are yours forever but you have a limited time to download the game on offer.

The first game in the promotion is the popular 2003 title, Prince of Persia: The Sands of Time. The next free game will be announced mid July.
