Today I bought the DLC that includes the flare revolvers. I had seen a video of them on youtube, and I thought they looked really awesome. Today have been nothing but killing floor. After a while I thought for myself that it would be really awesome to have an alt-fire for the flare revolvers. And since they are revolvers using flares as ammo, maybe the alt-fire could be to shoot bright, slow moving flares. They could be used to light up places, or signal friends of your location.
