#12 - Battle gyms...in CO-OP mode???

So, you and your friend are traipsing around catching Pokémon? Did you know you can joint forces and battle gyms at the same time?

That's right! You can join forces with nearby Pokémon Trainers to lay swigs to a gym. All you have to do is approach it at the same time, and begin the battle. You'll notice that there is now your Pokémon in the foreground, and your companions Pokémon in the background attacking the incumbent Pokémon. This works with up to three of you, so team up!

This is particularly helpful if your Pokémon aren't yet overly strong, your combined efforts should be enough to to help bring more powerful Pokémon guarding gyms to their needs.

See Haunter in the background? That's co-op baby!
