Invisible Mode is a game mode in Resident Evil: Revelations 2. It must be unlocked for each episode individually by simply completing the episode, and it can be purchased for 1000 BP per episode in the Rewards menu.
In this mode, all enemies are invisible. Moira's flashlight and Natalia's pointing ability can briefly reveal enemies. Like in the main campaign, Natalia is able to see an aura where an enemy is located.
