Another free DLC weapon is on the way to Splatoon 2. This week, players can pick up the Custom Splattershot Jr., a returning shooter from the first Splatoon.

Like all of the game's previous DLC weapons, the Custom Splattershot Jr. can be purchased using in-game currency from the Ammo Knights weapon shop. As its name implies, the shooter is a modified version of the standard Splattershot Jr. It features the same stats as the original gun, but it comes outfitted with a different sub-weapon and special.
