The flare-pistols in that have no expiry date (a handy 15HP damage item, ''if'' they hit, so I often save any I scavenge for a time my Action Points are low but I might appreciate a chance killing shot on a worn-down zombie) and are 'safe' to fire at all times - except for your target if hit, of course. Outside they can act as a signal, though never seen that as useful myself, but I always wished that inside a darkened building they'd at least be seen as a flash (maybe transient blinding) to anyone present but not hit by it. I mean, does ''nobody'' notice someone firing off a flare in an unpowered cinema, even the person it was aimed at but apparently just missed? (It was argued that a 'miss' was a misfire, a similar argument given with shotgun/pistol non-hits that no-one even hears, but they have no failure rate when deployed as signal.)
