Battling
With the controller of the different Gyms being solely based on who’s Pokemon emerge victorious from battle, it seems like the battling mechanic would be a good place to start with our explanations. When you come across a Gym that is controlled by an opposing team, you’ll be able to battle it. While there are certain things you’ll need to take into account (which we’ll get to later) before heading into battle, this is the meat of what you’ll be doing at the Gyms.
Battling has been largely refined from the standard Pokemon games, with a standard and special attack on offer and the ability to dodge your opponent’s moves. Tapping the screen will deliver a standard attack and holding down on the screen when the special meter has filled up will deliver the special attack. Swiping left and right on the screen allows you to move in each direction respectively to avoid incoming attacks. Remember to take a look at the defending Pokemon’s CP’s before you jump into battle, as if they’re too high above yours, you’ll likely come away pretty battered and bruised.
If you prove yourself in battle, however, and defeat all of the Pokemon at the Gym, you’ll emerge victorious and will be able to lay claim to it all for yourself.
