Flaregun (Item)

The Flaregun is a scrapped item in SP.

Functionality
According to TechnicalHost, the item would've fired a flare upwards, before exploding into numerous sparks. If the player were to stand near the explosion, they would get damaged by the sparks, or temporarily blinded by the explosion.

Availability
The item currently doesn't exist in the game, as it was scrapped early in SC-2's development due to it breaking the flow of SC-2's gameplay.

The item itself was eventually repurposed into the Glowstick.
