His blog entry details the expanding scale of the DayZ project, which is more or less running on a new engine. "We are moving to the server-client MMO architecture model. We are making weapons and items 'entities,' meaning we can support customization and variables assigned against items," Hall explains. "This is a massive departure from the previous engine. In many ways, once this phase is completed -- one could effectively say that DayZ is running on a new version of the engine. While the graphics may look the same (for now), under the hood so much is being completely rewritten."
