Version 4.3.0 for Splatoon 2 has been announced for a December 5th release. It will add two new gear abilities and some new weapons, and this will be the game's very last update to add new weapons:
- Bomb Defense Up DX, a new gear ability that combines the effects of Bomb Defense Up and Cold-Blooded. All existing gear with Bomb Defense Up or Cold-Blooded will be updated to have Bomb Defense Up DX instead, as will all ability chunks and drink tickets associated with these abilities.
- Main Power Up, a new gear ability that improves the performance of your main weapon. The specific improvements vary by weapon. For example: the Splattershot's firing accuracy while jumping is improved, the Aerospray MG's ink coverage is increased, the Splat Roller's damage is increased, and the Undercover Brella's canopy regeneration is sped up. What improvement is made to your main weapon can be checked in the customization screens.
- Ballpoint Splatling Nouveau (sub: Squid Beakon, special: Ink Storm)
- Nautilus 79 (sub: Suction Bomb, special: Inkjet)
- Custom Explosher (sub: Point Sensor, special: Baller)
- Bloblobber Deco (sub: Sprinkler, special: Suction Bomb Launcher)
- the last 4 weapons of the Kensa collection. At this time, the specific details are not officially confirmed.
