Ubisoft is giving away a free game every month to celebrate its 30th birthday

To mark three decades in business, French game developer and publisher Ubisoft, famous for titles including Assassin's Creed and Prince of Persia, is giving away games free of charge.

Every month for the next seven months, Ubisoft Club, the company's in-house equivalent to Steam, will be letting users download and keep a different PC title.

All gamers need to take advantage of this generosity is a Uplay account.

The first game being offered, Price of Persia: The Sands of Time is available now and is one of the company's all-time best.

Ubisoft will reveal the identity of the next free game in July.
