Corrupted Overworld turns all three Minecraft dimensions into one mixed survival landscape. Ordinary grass and oak forests can suddenly change into Netherrack, crimson vegetation, lava fields or End terrain without a portal between them.
Water, lava, Overworld blocks, Nether biomes and End materials coexist across the same map. The abrupt transitions make exploration unpredictable and force players to adapt farms, routes and shelters to whatever environment appears nearby.
Achievements remain available, so the world can be used for a full survival run instead of only visual exploration. The merged terrain also creates unusual building locations and faster access to materials associated with different dimensions.
