As Sharleen Spiteri once so memorably sang about this year's Eurogamer Expo, "She had a Halo, we really do adore her." Specifically, she was referring to all the amazing Halo 4 related stuff going on at this year's show!
What Halo 4 stuff? Well, you can enjoy the "Halo 4 Infinity Multiplayer" experience on the show floor, through the competitive multiplayer modes of War Games, so there's that. Halo 4 isn't out until 6th November, so it will give you a good head start on what will probably be this year's biggest Xbox 360 exclusive.
Given how important it is to Xbox 360 owners, Microsoft is also bringing over 343 Industries' Frank O'Connor to open the show in the 12pm (noon) developer session on Thursday 27th September. Frank will be doing a live demo of the game, talking about its creation and taking questions from the audience.
