23:46: As with previous games, it's out in November.
23:45: Ezio finally reaches his contact. "Sorry for the delay", he says, as the entire port is on fire. The demo ends with mysterious error codes and a shining gateway.
23:43: Running onto a boat, Ezio uses a flamethrower-like device to lay waste to the surrounding ships. Under attack, he then runs and leaps from boat to boat as they burn and explode around him, all in real-time. Fantastic stuff.
23:40: Headed through a market district, it certainly looks a lot more colourful than previous iterations. Moving towards a port, smoke bombs are dropped in battle, disguising Ezio, but he's able to continue fighting through an infra-red mode. He then detonates an explosive that takes down a watchtower, uses a zipline onto the pier proper, and fights another group of guards.
23:35: Assassin's Creed: Revelations is now introduced through a fantastic pre-rendered trailer, followed by the first gameplay demo.
23:34: Now Assassin's Creed gets the retro treatment - you know what's coming, folks.
23:32: Your Shape: Fitness Evolved 2012 is announced for November 2011, with a trailer that reveals it wants to burn one billion calories together - possible hints at a metagame element perhaps?
23:29: Here's Rocksmith, the guitar-teaching tool that was announced earlier this year, which is explained once more with a trailer. It's out in October across North America.
23:27: As someone just wrote on Twitter, "the epic conclusion to the trilogy". It's out on October 11 across all platforms.
23:25: Another retro throwback for a dancing title, this time revealing Just Dance 3 for Xbox 360 via Kinect, PlayStation 3 via Move and Wii.
23:23: A particularly inventive mini-game has players arrange themselves to form different shapes, including a UFO and Dracula. The gauge will fill as players successfully hold the pose, otherwise it'll wait for everyone to line-up properly. Afterwards, photos of the session can then be shared with friends on Facebook.
23:22: Rabbids for Kinect is announced. It has the annoying creatures appear from the floor in a Whack-a-Mole mini-game, which have to be stamped on. Rabbids: Live & Kicking will support four players simultaneously.
23:18: Now for ManiaPlanet, which features TrackMania, ShootMania and QuestMania, all of which will feature extensive sharing features. Trackmania 2 will be available later this year.
23:15: Both games will be connected in some form, where achievements will carry over from one to the other.
23:13: Now for the recently announced Ghost Recon Online, a free-to-play shooter for PC. The same announcement trailer is shown here.
23:10: With the enemies cleared, it turns out their job is to secure a VIP who has been held inside a fright container. With two players carrying the wounded individuals, the others provide cover as they make their way to a chopper. Another stunning demo from Ubisoft here.
23:08: The squad gun their way through the village and make their way to an oil harbour. Jumping forward, one player uses a drone to fly over the base and see where sentries are located, before engaging in a long-range firefight between cover points.
23:05: Time for Ghost Recon: Future Solder. The gameplay trailer sees a camouflaged squad in Nigeria. It features the same environmental text as last year's Splinter Cell: Conviction. As the player prepares to breach a building, it's revealed that three others are alongside him - we assume this means four-player co-op during the campaign.
23:03: Back to the crazy Mr. Caffeine, he shows us what Ghost Recon would have looked like 25 years ago. A lot like Syndicate , it turns out, complete with happy, chirpy music.
22:59: Moving quickly on, here's the film tie-in with Tintin. Peter Jackson and Steven Spielberg say that Ubisoft was a publisher well suited to creating a game in the universe. The gameplay will see players switch characters when they feel they're ready to move on in the campaign. The Adventures of Tintin: The Game is coming soon.
22:58: The trailer shows just that - four soldiers with unique abilities lay waste to a bar filled with Nazis in a comedic fashion. It's Brothers In Arms: Furious 4, coming 2012.
22:57: Gearbox Software's Randy Pitchford comes on stage to introduce his new project. It's a World War II shooter but with a twist, apparently.
22:53: Quietly strolling into a camp, a few knife throws takes out several patrolling sentries. A firefight quickly ensues, and after blowing apart a bridge, the player makes his way into a chopper and forces the pilot to take off before it's blown out of the sky. Recovering from the crash, he witnesses the same man who chucked him into the river. The demo ends - it's Far Cry 3, releasing 2012.
22:50: A hostage in the camp is executed, and the player is soon captured and thrown off a cliff whilst attached to a breezeblock. Freeing himself, he swims past dead people who suffered the same cruel treatment before heading to a river and taking out a guard. We should mention at this point that the visuals are absolutely stunning - we're also guessing that this is a new Far Cry game.
22:48: Ubisoft Montreal presents a new title - you're trapped on an island, your girlfriend is missing and everyone is crazy. The trailer shows a first-person view point, with the player crawling out of plane wreckage and using his camera to observe a nearby camp.
22:45: Finally, we get to Driver: San Francisco . A gameplay trailer shows off-road racing, the Golden Gate Bridge, car chases and lots of cars flipping over.
22:44: A trailer shows what Driver would have been like 25 years ago, complete with basic, bold colours and over-the-top view point. And disk-changing screens. Very cute.
22:43: He makes smutty jokes out of the Wii, 'Kinecting' with the opposite sex and something about "holding my joywand" (the Move). Er.
22:41: Someone dubbed Mr. Caffeine is welcomed on stage. He recounts what things were like 25 years ago, with pictures of Top Gun, the NES and the Master System.
22:39: The demo ends with a flying section, as both players jump on mosquitoes and pursue a floating steampunk pirate ship. The full game will feature four-player co-op and will be playable on the show floor.
22:36: The next area shows Tetris blocks falling from above, and the duo have to scramble through them and onto a platform above. It then cuts to an underwater area with singing jellyfish and screen-filling seaworms chasing both players. It's all a bit manic but looks to be a ton of fun, and again, the visuals are great.
22:33: He's here to show off Rayman Origins. Revealed at E3's conference last year, it's a high definition, co-operative side-scrolling platformer, and looks absolutely stunning. The demo consists of two players running their way through a maze, chasing a treasure chest on legs.
22:33: Famed designer Michel Ancel comes on stage and spouts some Shakespeare. The oddness begins.
22:33: We're off! CEO Yves Guillemot is welcomed to the stage and thanks the audience for a successful 25 years.
22:01: In the meantime, read our E3 predictions feature and discuss what you think Ubisoft has in store below!
22:00: Welcome to the live blog for Ubisoft's E3 2011 conference. This one's our personal favourite as the French publisher has the most bizarre and unexpected reveals - read up on last year's if you don't believe us. This year expect new Assassin's Creed: Revelations footage, more on Ghost Recon: Future Soldier and a possible Rainbow Six reveal. And Rabbids. Lots of Rabbids. We'll know more in 30 minutes time at 10:30pm BST / 7.30pm EST / 2:30pm PST.
