How to unlock the 炎の射手 achievement in Velvet Assassin - Definitive Guide
Once you find the flare gun simply kill 10 guards. It only takes 1 shot from the flare gun to kill each guard so just keep using the flare gun until the achievement unlocks, There is plenty of ammo later on in the game so this gun can be quite handy.
