Vortex Gaming

· The player begins a challenge to clear both Subnautica games in hardcore mode without construction tools.
· Base building, modification stations, and deep-sea modules are prohibited, and all progress will be lost with a single death.
· Players must survive in extreme environments such as oxygen deprivation, deep waters, and dangerous creatures, especially entering areas where survival is nearly impossible in the late game.

· Landing on 4546B, the challenge begins. The player extinguishes the fire on the crashed spaceship and collects basic resources.
· Essential gear such as a scanner, flashlight, repair tool, knife, fins, oxygen bladder, and oxygen tank are crafted while avoiding attacks from early threats like Crashfish.
· Blueprints for the Seaglide, Seamoth, and Mobile Vehicle Bay are found and crafted, marking the start of full-scale exploration.
· Considering how to explore the deep sea without base building, the player decides to build the submersible 'Cyclops,' which they dislike.

· The player explores shallow reef areas and the crash site to find the blueprint for the Cyclops submersible.
· During exploration, the Aurora explodes. To complete the engine core scan, the player crafts a laser cutter and radiation suit to enter the Aurora.
· Failing to find engine part blueprints in the cargo bay, the player moves to a more dangerous crash site to complete engine core repairs and remove radiation.
· The blueprint for the rocket 'Neptune' is secured, and to obtain the final Cyclops blueprint, the player explores a dangerous area inhabited by a Reaper Leviathan.

· The player builds the Cyclops and names it 'Bob,' but it is immediately damaged by fire.
· To explore the deep sea, the player crafts the Cyclops Depth Module MK1, repairs the submersible which caught fire again, and continues exploration.
· Arriving at a military platform, the player is diagnosed with the 'Kharaa' bacterium infection by an alien. This bacterium is a deadly plague that has killed 14.3 billion individuals on the planet.
· To survive without building a base, the player crafts numerous oxygen bladders and explores the dangerous 'Lost River' area.

· In the Lost River, the player discovers an alien base and acquires a blue tablet, activating a portal.
· The Ion blueprint is obtained, but it's realized that another blue tablet is needed to enter the final alien structure.
· To get two blue tablets, the player explores dangerous areas again, evading the pursuit of two Sea Dragons and reaching the final alien base.

· In the final alien base, the player meets the Sea Emperor and is asked to activate a portal for his children.
· Unable to activate the portal due to a lack of Kyanite, the player retrieves Kyanite while avoiding dangerous lava zones and Sea Dragons.
· The portal is activated, and enzymes are crafted by collecting samples of Peeper, Fungal, Sea Crown, Ghost Weed, and Scrutin.
· The hatched baby Emperors release enzymes, healing the planet, and the player also recovers. Afterward, the cannon is deactivated, a rocket is built, and the player escapes the planet.

· After clearing Subnautica 1, the player lands on 4546B again, but this time the spaceship explodes at the start.
· Facing new threats of extreme cold and oxygen deprivation, the player immediately crafts basic tools and an oxygen recycler.
· The biggest problem in Subnautica 2 is oxygen, and all algae play a crucial role underwater.

· In an alien ruin, the player meets a precursor named 'Alan' and infiltrates his mind.
· Alan asks the player to find three fragments to rebuild his body, which becomes the player's objective.
· To find Alan's body fragments, the player crafts a Prawn Suit, Depth Module MK1, Drill Arm, and Grapple Arm.
· Using the Prawn Suit, the player avoids the Ice Worms in the glacial zone to retrieve the first fragment, and then obtains the second fragment from deep within the Mushroom Caves.

· The player heads to the Crystal Caves, inhabited by Shadow Leviathans, and retrieves the final third fragment amidst the threat of the Shadow Leviathans.
· All fragments are collected to rebuild Alan's body, and the player returns to the final base to reunite with Alan.

· Alan reveals that he accidentally spread the 'Kharaa' bacterium, leading to the extinction of his species.
· Alan asks the player to follow him to Outpost Zero, and the player must traverse the Crystal Caves inhabited by Shadow Leviathans again.
· Boarding a massive spaceship with Alan, they leave 4546B forever, heading towards the truth about Alan's world and his species.

· The player successfully clears both Subnautica games under extreme conditions: without construction tools, safety nets, and with no room for error.
· This immense success brings great satisfaction to the player, but it also hints that future challenges will be far from easy.
