Earlier this month Hello Games announced that their title No Man's Sky will be getting a free update titled The Abyss but not much was known about it with Sean Murray saying that it "focuses on some of the eerier elements of No Man’s Sky, in keeping with the theme of this season."The update has been announced to be arriving for all platforms today, and it'll re-imagine the underwater gameplay bringing forth some scary moments. The Abyss is the first titled update since Next was released earlier this year and there are more in the works. The Abyss will be introducing aquatic environments with over five times more variety, varied creature behaviors, and improved visuals when underwater.Underwater biomes are improved with some rare exotic biomes being available to explore as your swim about. There are also more interesting and frequent creatures lurking the depths too with apparently terrifying creatures on the ocean floor. Sunken wrecks are also present and could contain ancient treasures, or buildings containing remnants of the lost occupant. They'll be sunken freighters to loot and with the terrain manipulator, you can excavate buried treasure. You'll also be able to repair broken star ships and get them in working order once more.You'll be able to achieve all of this while also completing the new story, "The Dreams of the Deep" which will bring a new, but dark narrative to No Man's Sky. The new mission will find players either discovering what happened to a troubled crew that became stranded after their freighter crashed, or they'll be exploring underwater ruins to locate a lost soul.It won't be a case of swimming everywhere though as you'll have access to a submarine type Exocraft known as the Nautilon. This vehicle can be summoned to any ocean on the planet and be docked at underwater buildings. The technology and style can be customized to suit your preference. In the blog post, it is also detailed that over a dozen new base parts have been introduced to allow more construction underwater.Marine shelters, glass corridors, viewing bays and multistory submersible view domes are a few to look forward to. There's even an indoor aquarium to decorate your land base, just in case you couldn't get enough of the fishy fish.No Man's Sky is available for PS4, PC, and Xbox One with The Abyss update launching today across all platforms.
