During an interview at E3 by senior producer Sara Jansson was discovered some new and interesting detail related to Mirror's Edge Catalyst . Jansson said that the Faith will have the chance to become invulnerable to enemy bullets. In practice, when Faith is locking in a move to perfection after another using her abilities, she becomes invulnerable and can be wounded only when stationary.

Faith cannot, as we know , collect any firearm left by enemies once they were slaughtered, as the developers have removed entirely the use of weapons in the game; This also because, remember, the development team wanted the game to focus more on fighting in first person melee.
