UPlay is an application for PC and Mac that will allow you to play video games online. Uplay is the Ubisoft client for purchasing, downloading and playing games from the developer. It offers an experience similar to gaming platforms like Steam of Valve or Origin of Electronic Arts.
Uplay is the required gateway to play PC versions of some Ubisoft games, whether you buy them in box or digital version. After installing a game, you are prompted to go through Uplay to activate your product key and start a game. You will not be able to launch it without going through Uplay! (And without creating an account).
With Uplay, you can access your entire Ubisoft video game library (for example the Assassin’s Creed series, Far Cry 3, Call of Juarez, etc.). The client is in charge of checking for any updates available for your games before launching them and installs them so that you get the best experience possible.
Uplay offers the possibility to add friends to send them messages, but also and specially to invite them to participate in online games.
Uplay is also a video game shop where it is possible to purchase and pre-order Ubisoft games and some of the titles from partner developers. Uplay also offers free content, including games like Trackmania Stadium, Anno Online and Might & Magic: Duel of Champions.
Being one of the most popular video game developers, Ubisoft has launched its own video game client called UPlay. This client is a service dedicated to digital distribution, communication, multiplayer and management rights for your games.
So, the more you use this client, the more points you can get that should be used to exchange different rewards.
