Nintendo is planning to put Pokemon on your phone sometime in the next month. No, it's not porting over the classic games just yet; the company's launching a new alternate-reality game called "Pokemon Go."

Developed by Google spinoff Niantic, "Pokemon Go" is a free-to-download game for iOS and Android that requires you to wander around the real world looking for pokemon to catch.

The game uses your phone's camera to project a pokemon model on the real world. One well-timed pokeball throw is enough to capture most pokemon; from there, the game lets you level up and evolve the pokemon you catch.

"Pokemon Go" also borrows some elements of territory control from Niantic's first game, "Ingress." "Pokemon Go" splits the player base into three different teams and lets them fight over control of real-world locations.

Nintendo is also planning to release a Fitbit-like gadget for around $35, though that won't launch until sometime after the main game. The device syncs up with your phone and is meant to let you play the game without walking around, looking at a screen the whole time.

For now, it looks like the game is limiting itself to the original 150 pokemon, but that might not last long. Two other new Pokemon games, "Pokemon Sun" and "Pokemon Moon," are set to launch in November this year with a whole new slate of possible pokemon to add.
