ShackNews was at the X05 Xbox 360 press event and has posted some details and screenshots about a couple of games. This includes Dead Rising, Mass Effect, The Outfit and Project Gotham Racing 3.
I have to start with what I thought was the most fun game on display at X05, Dead Rising. In the demo of Capcom's third person zombie action game, you take control of Frank, a photojournalist who is trying to find out more about what has infected all these people. You find yourself in a shopping mall full of the undead, and you're supposed to find a woman who has information about the infection. Along the way you meet other characters (who are standing on top of food stalls), to whom you can speak and even accept side quests from. But really, it's all about the satisfaction of mowing down zombie after zombie.The screenshots of these games are stunning. Check it out over here.
