About this Mod
Cobblemon: Shadowed Hearts brings Shadow Pokémon from the GameCube-era classics Pokémon Colosseum and Pokémon XD: Gale of Darkness into Cobblemon.
Shadow Pokémon wield powerful Shadow Moves, but at a cost. Their hearts are closed, limiting move access and behavior until they are purified. Shadowed Hearts faithfully recreates these mechanics while remaining highly configurable for both singleplayer worlds and multiplayer servers. Many systems are designed to closely mirror their original GameCube implementations.
Features
- Shadow Pokémon with authentic restrictions and Shadow Moves
- Heart Gauge mechanics
- Snag Machines (PvE-only for now)
- Hyper Mode and Reverse Mode
- Call button mechanic
- Shadow Pokémon purification system
- Relic Shrines
- Purification PC with Flow and Tempo mechanics
- Scents to influence purification, with an optional expanded scent system
- Aura Reader for locating nearby Shadow Pokémon
- Utilities for server owners and map makers to assign Shadow Pokémon to NPCs
- Shadowfall Meteoroids that generate in the world and can gradually convert nearby Pokémon into Shadow Pokémon
Planned Features
- Expanded configurability
- Expanded and refined visuals and sound design
- Additional structures, including Outskirt Stand from the GameCube games
- Expanded and enhanced Shadow Moves
- Deeper custom lore and a structured story questline
- A story-focused custom dimension featuring voiced NPCs
- Instanced, randomly generated dungeons in a dedicated dungeon dimension with unique objectives
- And sooooo much more!
Shadowed Hearts is designed to preserve the identity of the original Shadow Pokémon experience while expanding it into a modern Cobblemon mod with flexible configuration options for a wide variety of playstyles.
