Sega had a really nice setup. Make your way through their booth, play three of their demos (MadWorld, House of the Dead Overkill and The Conduit) and you get a T-shirt. Well… acquired.
The Conduit was the second game Kombo played at the show, considering the possibilities for an obnoxious line. You remember the footage of a giant bug monster, alien thing smashing down on a bridge and you fighting it? That's the demo. It's pretty much find the hive and kill some alien jerks.
