The Spark Shot (スパークショット supākushotto ) is an experimental weapon developed by Umbrella for dealing with unruly B.O.W.s.
It is basically a large-sized stun gun with an effective range of 10 feet. Its ammunition count is represented as a percentage. Its initial ammo is 100%, and each shot takes up 5%. It takes up two inventory slots.
This weapon has one good purpose; help Claire defeat the Birkin G-Mutation. Though the weapon is strong against Birkin, it only does average damage against most other enemies, giving it little value beyond this encounter.
The Spark Shot can hit enemies on the ground without having to aim down due to its wide spread. No spare ammo can be found for the weapon in the entire game, making it useless once empty.
The weapon was originally known as "Air Taser", according to hacked files found within the game's Trial Edition, and it was supposed to have additional ammo like the submachine gun, but its name was changed and the ammo was removed prior to the final release. Its names were written in Japanese, and are believed to have been placeholders.
