Flares can be obtained from the Grocery Store (although it is rare) or from The Director and the first three are free and more can be obtained by trading him ten bullets, however he will stop providing flares after facing the Mother for obvious reasons. Used to light up rooms and stun Monsters. Can also be quickly placed with the "1" key. Using flares is a good way to obtain a Green ending as you can avoid combat entirely by stunning monsters instead of shooting them.
