Game Description

It is a complete, hardcore difficulty hack designed for players who loved the brutal challenge of games like Emerald Kaizo. This game keeps the classic Hoenn story and map intact but massively ramps up the difficulty with champion-level AI and Gym Leaders who wield teams of six powerful Pokémon, including Legendaries and Mega Evolutions. To help you survive, you start with a powerful Dragon-type Pokémon and are given infinite Master Balls and healing items for use outside of battle. With a massive roster of Pokémon from Generations 1-8 and a strict ban on setup moves and in-battle items for the player, this is the ultimate test of pure strategic skill.
