Ubisoft have released details of launch day events, midnight opening and multiplayer previews in the UK for Assassin's Creed: Brotherhood which will be launched on November 19th.
"From Monday November 15th at all major HMV GamerBase locations you'll be able to play the full multiplayer version, a thrilling game of hunter and hunted between well-armed Templars. That's a whole week of playing multiplayer assassination before anyone else!
On November 18th, we'll also be doing midnight launches! Gamers will be able to play the single player story mode from 9pm until midnight (bring your memory cards!), at which point you'll be able to buy the game for yourself. GamerBase will be running midnight openings on November 18th at its London Trocadero, Glasgow, Manchester and Reading locations. There will also be a few Assassin's Creed prizes up for grabs."
In addition to the above, from the 19th to the 25th of November, Assassin's Creed Brotherhood will be available in it's entirety to play in all Gamerbase centres.
