Ubisoft has joined the likes of Valve and EA by adding digital content delivery to its Uplay service.

The new client allows users to purchase, launch, and play games, as well as use Uplay's existing friends list and chat services.

The system will replace individual game launchers for all Ubisoft PC titles.

"Uplay PC is a great way for customers to discover Ubisoft's games, connect with their friends and gaming communities, and win achievements and content that's not available anywhere else," said Ubisoft’s worldwide director for online games Stephanie Perotti.

A launch promotion for the service has certain titles priced at US$1 (AU$0.95) each, such as Driver: San Francisco, From Dust, Silent Hunter 5, and HAWX 2.

"For PC gamers that are already fans of Ubisoft's titles or have been considering trying some of our classics, this promotion is a great deal, and our way of saying thank you for their support," said Perotti.

Last month, Ubisoft raced to patch a security vulnerability found in Uplay after it was discovered by a Google engineer.
