Mirror's Edge Catalyst Senior Producer, Sara Jansson, during an interview with DualShockers' Giuseppe Nelva at Gamescom, explains how the team at DICE made the city of glass feel alive using the Frostbite engine and the combination of three reflection technologies.

Mirror's Edge Catalyst combines three reflection technologies making the city of glass feel alive

　　For us it was really important to have that, because since the world is so clean, we need to have that to make sure that it actually comes alive. In many other games we can hide stuff with dust or grit or dirt, here everything is so nice and clean and pristine. We invested quite heavily in this feature when it comes to rendering, and in many other features.

The streaming technology used for Mirror's Edge Catalyst enables fluid movement throughout the city without any loading screens

　　Also, Mirror’s Edge is quite different from other Frostbite games, since first of all we’re not physics-based, we’re more animation-based, and we’re also not building the game on huge terrains, like Battlefield, we’re actually building buildings, and everything is interactable, because everything is gameplay basically. So I think that the streaming technology of Frostbite was really important because we has this huge vista, which is a city. Everything is made of objects and you need to interact with everything.

　　So the streaming technology… Without that we couldn’t be doing this without any loading screens, fluidly moving through the city.

　　It’s actually really advanced to build this type of city. I think that the engine was at the start built for huge terrains, not for huge cities with millions of objects with them. That has been kind of a challenge. We worked together with Frostbite on how to do that, so that we could actually build this big city which is all about gameplay.

　　Mirror’s Edge Catalyst will be available on February 23, 2016, at retail and for digital download on Xbox One, PlayStation 4 and PC.
