The title "Mirror's Edge Catalyst" was formally announced in June 2015 prior to E3 2015; DICE product manager Sara Jansson affirmed that the game is not a sequel but would delve into more of Faith's past while expanding on the original game's first-person perspective experience. On June 15, at E3, and later on the "Mirror's Edge" YouTube channel, DICE released a new trailer for "Mirror's Edge Catalyst", revealing elements of the game's storyline and environment. It was confirmed that the game would feature an open-world design and Faith would no longer be able to use guns.
