Dead Rising 3 began life as an Xbox 360 title, but the game's scope was too much for the ageing console to cope with, Capcom Vancouver producer Mike Jones has told Siliconera.
"In terms of building the game, we originally developed it on PC and everything we were doing was breaking the bank on [Xbox] 360," explained Jones. "The number of zombies, the streaming stuff we wanted to do, memory budgets for the number of environments and items and physics and all of that stuff. Our tech team partnered with Microsoft to get early specs and figure out how we were going to get it on new hardware."
The decision to move the project to Xbox One has enabled Capcom to do so much more with the game.
"The biggest things for us have been the size of the world, the density of the world, the streaming spaghetti of getting everything working with no load zones and seamlessly streaming," said Jones. "Also, how we build missions in a much larger world like that – how we send you to different districts and how we get you to explore all of these nooks and crannies in the environment."
Microsoft's tech team has been on hand throughout the transition to ensure the launch game makes the most of what Xbox One has to offer.
"They get our builds all the time and helping us optimise it and helping us with performance stuff," said Jones. "They visit us every week. We go down there every other week. We've been essentially merged together.
"They have done custom work with multi-threading for us. All of the Kinect things, we're making a game for hardware that isn't finished that we're all trying to launch together on day one. Basically, we've been in lock step with them."
The game's certainly starting to take shape as a next-gen game, as you can see for yourself in the latest dev diary.
