Here's some Pokemon GO beta gameplay

• There will be no battles against wild Pokémon, instead you simply catch them directly using various Poké Balls
• Trainers are customizable with different options
• 137 different attack names have been found in the game’s code, confirming battle systems. Some of the moves include Flamethrower and Hyper Beam.
• There are an additional 95 “fast” versions of the discovered 137 attacks.
• Players will receive a starter Pokémon, though in the beta version this does not happen.
• A new game function with the name “Starburst” has been discovered – details surrounding it are unknown.
• References to Google Cardboard, a mobile VR peripheral, have been found within the game’s data.
• There are three “teams” the player can join: Red Team, Blue Team, or Yellow Team.
• Only first generation Pokémon exist in the beta; it’s unclear if this will be the case for the final version of the game.
• There are multiple versions of the defense stat, though the reasoning behind this is unclear.
• There are seven object categories: Poké Ball, Potion, Revive, Maps, Battle Objects, Food, and Camera. Food and Camera details are unspecified.
• The following items are the only ones available in the beta: Poké Ball, Great Ball, Ultra Ball, Master Ball, Potion, Super Potion, Hyper Potion, Max Potion, Max Revive, X Attack, X Defense, X Miracle, Razz Berry, Bluk Berry, Nanab Berry, Wepear Berry, Pinap Berry, and Special Camera.
• X Miracle is a new item. Its effects are unknown as of right now.
• Pokémon Natures are present, but differ from the main games. Currently, the ones found are: Stoic, Assassin, Guardian, Raider, Protector, Sentry, and Champion. Their roles are currently unknown.
• Microtransactions are available.
• A day-night cycle is confirmed.
• Normal, Legendary, and Mythical Pokémon are all present, and Pokémon are categorized as such.
• There is no evidence of Mega Evolution, however it’s unknown if this is only true for the beta.
• Supposedly, Pokémon are only allowed two moves during Gym Battles.

Stupid non Japanese dev, WHERE THE FUCK IS GREEN!!! Why would you choose Yellow over Green here -_-

*Picks Team Yellow*

#TeamYellow !

Team Yellow, obviously :P. I'm not convinced about not having the possibility of weakening the Pokémon in order to catch them, but I guess that's where micro-transactions are. Pokéballs.

A lot of details emerging from data miners for Pokemon Go Beta testing so that is nice..

Game should be interesting, but I don't see myself playing this game much though
