Breaking news from the Squid Research Lab! The Splatoon 2 game will soon be receiving three new updates. Manta Maria joins the lineup of Turf War* and Ranked Battle stages this weekend, while the Bubble Blower special weapon will become available in a set with the Forge Splattershot Pro starting Sept. 1. Finally, the Lost Outpost stage joins the roster of Salmon Run stages later today after players apply a software update. Please note that release timings noted in the subtitles are based on European time zones.

All of them are looking good!!!

Finally. Was waiting for a new map.

Great news!

Bubble Blower looks sick af. Is it a special weapon?

Yes it is.

I hope we can get a return of Killer Wail, Ink Strike, and Kraken.

Also, a return of the lobby minigames.

A lot of people are saying they need to nerf Tri-Sloshers. Damn. I co-mained them with the Ink/Octobrush and N-Zap weapons. Anyway, Manta Maria is fucking awesome. One of my gripes with Splatoon 1 was they had such creative stage names like "Museum D'Alfronsino" (?) and I was never engrossed or resonating with that premise. This is clearly a ship stage. I hope Nintendo stay loyal to the stage theme design-wise from now on.

If I'm not mistaken, the update is up now, so we should learn just in a few more minutes if the Tri-Slosher received its nerf. 

EDIT: Just checked the patch notes and it seems like nothing happened with the sloshers. Cheeky bastards. 

And yeah, the new map is awesome, and so is the newest special weapon.
