A common household flashlight. Makes for a powerful tool against demons, as it so happens.
FAITH: Deluxe Edition
One of the new features for FAITH: Deluxe Edition is the flashlight mode, which plunges the entire map into darkness. This requires John Ward having to use the flashlight to see not only where he is going but whatever may attack him. The purpose is to add a much more difficult experience to FAITH.
FAITH: Chapter II Demo
FAITH: Chapter II
Once again the flashlight returns, except it is used substantially more in Chapter II. Once again, John must use the flashlight to find and ward off a demon in a dark portion of the Candy Tunnels. Then John must use the flashlight to keep Thralls at bay while he attempts to exorcise a mysterious portrait.
