Microsoft Game Studios and the Eurogamer Network have today confirmed that Halo 4 will not only have playable multiplayer code on the show floor during this year’s Eurogamer Expo, but  also that  343 Industries‘ Frank O’Connor will be opening the show with a developer talk at noon, 12PM on Thursday 27th September.

The 343 Industries head-honcho will be showing a live demonstration of the highly anticipated shooter, alongside imparting his experiences with the Halo franchise and indulging in a bit of Q&A with the audience.

The epically awesome news that Halo 4 would be the Expo in both playable and developer session form, follows hot on the heels of the release of samples from the game’s soundtrack which you can stick in your ears here.

Tickets for the Expo can still be bought by clicking on the logo below, but be quick; they’re starting to run out.

Its shaping up to be a cracking show. No ticket? Sort it out.

The Eurogamer Expo is due to take place this year on September 27-30 at Earls Court in London.
