IRON OCEANS | Blood oceans inspired by Iron Lung | Polytone required! | PaleoTech |

Minecraft's oceans have always held a quiet mystery, but what if they turned into a nightmarish sea of blood? The IRON OCEANS | Blood oceans inspired by Iron Lung | Polytone required! | PaleoTech | resource pack does exactly that, plunging your Overworld into a dread-soaked abyss reminiscent of the claustrophobic horror game Iron Lung. Every river, every deep ocean biome, and the very fog that shrouds them becomes a visceral crimson, turning routine underwater trips into pulse-pounding descents.

What Makes This Blood Ocean Pack So Unsettling?

Inspired by the oppressive atmosphere of Iron Lung, this pack overhauls the visual identity of water. The default blue hues are replaced with deep, murky reds that shift and darken with depth. Fog no longer offers a soft veil but a thick, blood-tinged curtain that limits visibility and amplifies tension. The result is a complete sensory shift: you're not just swimming, you're wading through an alien, hostile environment. The pack leans heavily on PaleoTech's signature style, blending prehistoric dread with aquatic horror.

Key Visual Transformations

• Ocean and River Water: All surface and underwater colors are retextured to a rich, unsettling blood red, with gradients that grow darker as you descend.
• Fog Overhaul: The atmospheric fog is tinted to match the blood oceans, reducing visibility and creating a constant sense of foreboding.
• Biome-Specific Tweaks: Different water biomes receive tailored crimson palettes, ensuring variety while maintaining the horror theme.

Essential Requirements: Polytone and Minecraft Version

To achieve these dynamic color shifts, IRON OCEANS | Blood oceans inspired by Iron Lung | Polytone required! | PaleoTech | relies on the Polytone mod.

Using it on other versions may cause visual glitches or outright failure, so stick to the recommended range. Because Polytone's formatting can conflict with some third-party launchers, manual installation is strongly advised.
