What it is
Grand Colosseum is a hack of Pokémon Colosseum by Kya, first released in November 2021 and updated to version 3.1 in February 2024. It makes one of the toughest Pokémon games tougher still, while smoothing out many of its old annoyances.
What's changed
- The physical/special split, the Fairy type and 65 new moves
- Updated stats, types and abilities, a revamped TM list with eight new TMs, and reusable TMs
- New Shadow Pokémon encounters and Gym-themed Colosseum battles
- Regional forms such as Alolan Ninetales and Marowak and Paldean Tauros
- The PC box can be opened anywhere, so you can save wherever you are, and a new interface shows whether a move is physical or special
- A nuzlocke mode, added in version 3.0
It comes in three versions, Johto, Kanto and Hoenn, which differ in the starters and legendary trio you can get.
