Activision is attempting a world record for the launch of Guitar Hero 5 across Europe today. A 24-hour continuous party play marathon is taking place as we speak in France, Italy, Sweden, Spain, Holland and at HMV Oxford Street in the UK with the challenge to get through as many different participants as possible.\nBritish pop artist, Pixie Lott was down there among the regular punters pulling her rock face alongside some other pretty intense looks of concentration in the gallery below. If you're out and about in London today, you might also see the Guitar Hero Brit Bus - the black-painted, converted doubledecker kitted out with a full set of instruments for the public to get on board and have a go with. There's also refreshments available although not a very rock and roll looking rider when Pocket-lint was there.\nThe marathon is designed to show off the latest editions Party Play mode which allows gamers to jump in and out, pause and change difficulty during a track without having to halt the session for the whole band. No one from Activision was available to comment on the latest game battle of the war between Rock Band and Guitar Hero but the fact that HMV had branded the outside of its shop in the Harmonix Beatles can't have gone down too well with today's guests.\nThe record attempt will continue from 11am today until the store closes at 7pm and for one more hour form opening time at 10am tomorrow - so long as the cleaner doesn't switch the console off tonight, that is.
