Players can expect a linear progression filled with strategic risk-reward decisions and tough battles. Read below for a more detailed overview of the features!
Features
- Enhanced Difficulty
Pokemon Billowing Emerald significantly ramps up the difficulty, comparable to hacks like Vintage White, Ancestral X, and Sterling Silver. It’s made for Nuzlockers, providing a challenging yet achievable experience. - Double Battle Bosses
Every major battle, including gym leaders, rival battles, evil team admins, and Elite 4 members, will be fought as a double battle. To keep the game fresh, single battles with mini-bosses and trainers still occur on routes. - Expanded Pokemon Pool
You’ll have access to nearly all 386 Pokemon, allowing for a diverse team composition. Your starters include Chikorita, Torchic, and Squirtle, with an additional second starter available in Oldale Town from the remaining six Pokemon. - New Regional Forms
Several classic Pokemon have been replaced by their respective regional forms, including Raichu, Sandslash, Meowth, and more, offering a new twist on the original lineup. - Rebalanced Pokemon
Many Pokemon have received stat, ability, and learnset changes. Some even have new typings! These adjustments ensure that all Pokemon, even the less powerful ones, remain relevant and viable throughout the game. - Handcrafted Level-Up Learnsets
Every Pokemon has a completely custom level-up learnset. The game’s difficulty is balanced around these personalized learnsets, making each Pokemon’s progression unique. - Four New Recurring Characters
You’ll encounter four new recurring characters early in the game, each playing a significant role in the story. While their identities are kept under wraps, expect some interesting interactions and battles with them. - Gauntlets
Inspired by hacks like Garbage Green, certain areas of the game (such as Routes 116 and 109) feature Gauntlet challenges. Players will be locked into these areas and must face tough battles with no way out until they complete the challenge. - Quality of Life Features
To make your experience smoother, the game includes several quality of life improvements, such as reusable TMs, running indoors, infinite access to crucial items, and even overworld PCs on long routes. These changes ensure a fluid and enjoyable playthrough. - Thorough Documentation
As a nod to Nuzlockers who need precise information, the game includes comprehensive documentation. Every encounter, trainer, move set, item, and more is detailed, making it easy to plan your strategies and progress.
