UBISOFT® CONFIRMS UPLAY® PC 4.0 FEATURING INTEGRATION OF VIDEO PLATFORM TWITCH

Uplay Will Also Be Integrated Into Next-Gen Consoles

SAN FRANCISCO – September 19, 2013 – Today, Ubisoft announced the latest PC version
of its cross-game, cross-platform service Uplay. Uplay PC 4.0 will be available for
all members in October 2013.

Uplay PC 4.0 offers an array of new features in high demand among the PC community.
The integration of Twitch, the world’s leading video platform and community for
gamers with more than 45 million unique visitors a month, enables members to
broadcast their in-game videos and share some of their most memorable gaming
achievements with friends. An improved download manager allows for the progressive
download of games and auto-patching, meaning that gamers can spend more time
playing. And a new social wall keeps members up-to-date on their friends’
activities. 

Ubisoft also confirmed that Uplay will be available when Xbox One, the all-in-one
games and entertainment system from Microsoft, and the PlayStation 4, Sony’s
next-generation computer entertainment system, arrive in stores later this year.
Using one unique profile, new and existing Uplay members will be able to seamlessly
access the full scope of Uplay services and features on next-generation consoles.
Above all, gamers will benefit from the Uplay Win program, which rewards fans for
their commitment to Ubisoft’s brands, both in-game and in real life with additional
in-game content such as items and accessories, and invitations to consumer and
industry events. More than 40 million rewards have been redeemed to date. All of
Ubisoft’s next-generation games, including the highly-anticipated Assassin’s Creed®
IV Black FlagTM, Just Dance® 2014, The CrewTM and Watch DogsTM will integrate Uplay,
including Uplay Win.
