The game's developer, Niantic, has announced that a number of long-awaited features are to be added to the 'Pokemon GO' attractions overt the coming months, including fully revamped Gyms and Gym Badges.

In a press release, Niantic said: "Gyms will now feature six permanent slots that can be filled by the controlling team's Pokémon, and opposing teams will battle Pokémon in the order they were assigned to the Gym.

"The new motivation system introduces an interactive factor for Pokémon assigned to a Gym that will impact their potential Combat Power (CP).

"Pokémon defending a Gym will lose motivation over time and as they are defeated, lowering their effective CP and making it easier for opposing teams to defeat them. However, Trainers from the same team can give defending Pokémon Berries to keep them motivated."

It has been announced, too, that the new Raid Battles feature will allow gamers to team up with their friends to tackle bosses for sought-after rewards.

Of the new development, Niantic said: "Trainers will have the opportunity to team up with others nearby and work together to defeat extremely powerful Pokémon known as Raid Bosses.

"Raid Battles are timed in-game events that will temporarily take over a Gym, providing Trainers from all teams the chance to visit the Gym and group up together to challenge the Raid Boss and potentially earn special new items along with an opportunity to catch these Pokémon."
