Another new weapon hits Splatoon this evening at 10 p.m. ET / 7 p.m. PT, as the Luna Blaster will become available.
According to the experts at the the Squid Research Lab, the Luna Blaster is a rapid-fire weapon with explosive impact, but is more of a short range weapon. Ink Mines will be the sub-weapon, while the special move is the longer-range Inkzooka.
Data miners have located a Neo version of the Luna Blaster that employs the Splat Bombs and the Bomb Rush special, but that weapon will be unlocked at a later time.
