Orion 12 Gauge Flare Gun (cut)
Sometime after Freeman has left Kleiner's Lab, a Metrocop fires a flare in the Canals to summon his colleagues. Another Metrocop fires one when Freeman assaults a power generator during the City 17 uprising. Overwatch Soldiers shoot flares along the Coast to summon a Gunship and to light cell block D8 in Nova Prospekt after turning off the lights.
 Behind the scenes
Each time a flare is shot, the shooter is invariably out of the player's reach to prevent them from seeing any flare gun. When looking closely, it appears that no flare gun model is used, nor is in the game files (the Metrocop in the Canals for instance merely uses its standard pistol). An unused HUD icon for the flare gun can be found in the Half-Life 2 files.
The weapon was originally to be used by the player to ignite targets. It can be found and used only on the test maps in the Half-Life 2 leak. When shot, the flare sticks to the player when approached and can damage their health. It was likely to be found only in the Arctic levels, and at least on the Borealis and in Kraken Base, always stored in "pyrotechnic lockers". There is an unused model version of the locker intended to be used by the player in the files. Disposable emergency flares were also originally to appear in Half-Life, and were finally introduced in Episode One.
