The week's Splatoon update will go live tonight at the standard time (10 p.m. ET, 7 p.m. PT) and will bring a modified version of an existing weapon.
The H-3 Nozzlenose is a heavier version of the L-3 Nozzelnose family of weapons, which trade a bit more power for slightly less speed. The sub weapon is the Suction Bombs and it has the Echolocator special.
This new weapon will launch just in time for the next Japanese Splatfest, scheduled for this weekend.
