This alpha test build of the game will feature 52 stages, 15 floors of the Champion Tower to climb, and 134 different Pokemon to discover. Additionally, PokeLand will feature new islands to unlock, as well as a detector that can be used once every 30 minutes to help you locate Pokemon. Players will also be able to power up their figures using the in-game Gear and P they've acquired. PokeLand will also require an internet connection to play.
