From the press release:

    OnLive, Inc., the pioneer of cloud gaming, announced today that the universally acclaimed action-adventure game Batman: Arkham City is now available for instant, on-demand play on the OnLive Game Service, along with a FREE, EXCLUSIVE instant demo—giving Batman fans in the US and UK access to the first 30 minutes of the full game. While today marks the launch of both the game and demo in the US (in line with Warner Bros.’ North American PC release), the demo precedes the UK’s official PC launch by three days (the game will launch in the UK on November 25, 2011), giving UK PC and Mac gamers their first chance to play the game through an exclusive, fully playable preview that can only be found on OnLive. As with all OnLive games, Batman: Arkham City can be played instantly on HDTV and almost any PC or Mac®, with no discs, no large downloads and no high-performance hardware required.

    Developed by Rocksteady Studios, published by Warner Bros. Interactive Entertainment and based on DC Entertainment’s core Batman license, Batman: Arkham City has received critical acclaim for its console versions, with average scores of 94 to 96 on, and is already a contender for “Game of the Year”awards . Batman: Arkham City builds upon the intense, atmospheric foundation of Batman: Arkham Asylum, sending players flying through the expansive Arkham City—five times larger than the game world in Batman: Arkham Asylum—the new maximum security “home” for all of Gotham City’s thugs, gangsters and insane criminal masterminds. Featuring an incredible Rogues Gallery of Gotham City’s most dangerous criminals including Catwoman, The Joker, The Riddler, Two-Face, Harley Quinn, The Penguin, Mr. Freeze and many others, the game allows players to genuinely experience what it feels like to be The Dark Knight delivering justice on the streets of GothamCity.
