ARK Astraeos Map Guide: Regions, Resources and Creatures

 

    Astraeos is a paid expansion map for ARK: Survival Ascended. Per ark.wiki.gg it's "a paid, official, and non-canonical DLC expansion map" that "was released on February 14, 2025, on Steam, PS, and Xbox" for $14.99; Epic Games Store players waited longer, with an EGS release of October 22, 2025 — just over eight months later. This guide covers what the map actually is, its eight documented regions, how teleportation works, and its creature and boss roster, all pulled directly from ark.wiki.gg's Astraeos page.

 

What Is the Astraeos Map?

 

    The wiki's Overview calls Astraeos "a sprawling 264 sq km Greek-inspired map: With over 70 sq km ready to explore at launch." Doing the arithmetic: 70 ÷ 264 ≈ 0.265, so only about 27% of the map was open at launch, filled in over later updates. Notes/Trivia confirms the staged rollout: "Astraeos marks the second map that was not complete upon its launch release, but was a work-in-progress. The first was Ragnarok on ARK: Survival Evolved in 2017," and "On August 27, 2026, Astraeos was officially completed." The wiki also calls it "currently the largest Map to date," themed around "Greek mythology."

 

    The source describes "landscapes inspired by the Mediterranean coast, the serene beauty of cherry blossoms, and the rugged terrain of Appalachia," a dynamic weather system with storms, "dozens of caves," and "Ancient Greek ruins and sacred temples." Development credit goes mostly to modders: Astraeos "was almost entirely developed by modders," per the wiki, naming Myrmcoleon, Hazearil, and Dragonheart for specific creature/boss work, with Nekatus as the map's creator — Nekatus's third mod to go official after Valguero and Fjordur.

 

 

The Eight Regions of Astraeos

 

    The per-region breakdown comes from the wiki's "Unique Environmental Features" list (the page's own dedicated "Regions" header is actually blank, so this is where the real detail lives):

 

• Korinthos — "open plains, marble cliffs, temperate forests, warm beaches, and overall comfortable climate." A campsite at (61, 23) has crates for Primitive-tier Metal Hatchets, Metal Picks, and Crossbows.
• Phokintos — "cold plateaus and forest in the north and warm plains and beaches in the south," plus an eastern bioluminescent swamp. Hosts an Aberration Blue Zone cave with Blue/Red Gems, Rock Drakes, and light pets.
• Therokis — "a volcanic island which is the fiery home of the ferocious lightning creatures and the Boaratos," with Element Veins, Orbital Supply Drops, and a roaming worldboss.
• Lemnokis — "mainly beaches, redwoods, tundras, and mountain ridges," with an Aberration fertile cave holding Gas Veins, Green Gems, Karkinos, and Cosmo.
• Pyranthos — "a vast desert landmass shaped by myth, ruin, and survival," with ruins "haunted by Skeleton Warriors."
• Helianthos — "towering mountain ridges, open flower-filled plains, peaceful creatures, and flying islands suspended high above the landscape."
• Abyssanthos — "a fog-shrouded deep-sea expanse with enormous underwater air bubbles supporting a mythical underwater city," built for base-building beneath the surface.
• Astraeos Sea — "dynamic wave physics, hostile ship enemies, deep-sea trenches, underwater caves, and plenty of other underwater regions."

 

 

Getting Around: Teleportation and Spawn Points

 

    Astraeos ships with built-in fast travel instead of an obelisk network. The wiki describes "a Teleporting system for fast travel between all the spawn areas on the map," used by holding R (PC), X (Xbox), or Square (PS5) to "open the radial menu and choose your destination." The source's "Approximate Spawn Locations" entry is a reference map image, not a written coordinate list, so beyond that image the exact spawn coordinates for each region are undocumented in text form — the radial menu, not a memorized coordinate, is the reliable way to reach a region.

 

Creatures, Bosses and Corrupted Variants

 

    The wiki names three headline tames with full descriptions: the Maeguana, "a striking Maewing variant" whose "nurturing instincts aid in raising baby creatures" and whose "skin membrane allows for graceful gliding"; the Grand Tortugar, "a giant tortoise-like creature that serves as a mobile stronghold," with a natural "shelter" beneath its shell; and the Boaratos, "a large hog-like creature that combines raw physical strength with fiery attacks." The Unique Creatures list adds seven more names — Kirayli, Minotaur, Pulmonoscorpius Monarch, Rhyniognatha Drone, Shark, Skeleton, and Squid — with no further description, so what distinguishes each beyond its name is undocumented here.

 

    Above the standard roster sit two enhanced tiers. Astral Creatures "act as the map's Alpha Variants with their own unique design and rewards" — the source's list names 13, including Astral T-Rex, Astral Mosasaur, and Astral Rock Drake. Lightning Creatures are "a Corrupted Creature variation for Astraeos" that "appear exclusively on Therokis" — the list names 18, from Lightning Giganotosaurus to the Enraged Lightning Rex.

 

    For bosses, the wiki's dedicated Bosses list names only Manticore, but Notes/Trivia separately confirms Astraeos "has the most Bosses of any map with 6 Bosses and 4 minibosses and a worldboss," naming two Ascension encounters added later — Abyssalus the Void Beneath and Shallocis the Void Above — plus minibosses Colossus and Kroaratos. The full boss roster is documented across those two sections, not the short Bosses list alone.

 

 

Practical tips

• Use the radial teleport menu (hold R / X / Square) — Astraeos doesn't rely on an obelisk network like older maps.
• Head to Therokis specifically for Lightning-variant creatures; the source lists them as exclusive to that region.
• Grab Primitive-tier gear fast from the Korinthos campsite at (61, 23).
• Only about 27% of the 264 sq km map was open at launch (70 ÷ 264) — later regions arrived over subsequent updates.
• Check Notes/Trivia for the full boss list — the short Bosses field alone only names Manticore.

 

Running your own ARK server

 

    Hosting Astraeos on a dedicated ARK server means your tribe can explore all eight regions together on a schedule that doesn't depend on one person's game staying open. A persistent server keeps Trireme runs, Therokis Lightning-creature hunts, and boss progress saved exactly where you left them, and full config access lets you tune taming and harvest rates or manage the DLC's mod-derived content without touching anything on your own machine.

 

Conclusion

 

    Astraeos packs a 264 sq km Greek-inspired world, eight distinct regions from volcanic Therokis to the underwater city of Abyssanthos, a built-in radial teleport system, and a creature roster spanning ordinary tames, glowing Astral Alphas, and Therokis-exclusive Lightning variants — with a boss list the source itself splits across two different sections.
