Pokemon Go's string of Safari Zone live events are scheduled to begin soon across Europe. Today, developer Niantic shared more details about the forthcoming meet-ups on its website, including what kinds of Pokemon players will have a chance to encounter.

On September 16, Unibail-Rodamco Shopping Centres in Oberhausen (Germany), Paris (France), and Barcelona (Spain) will host the region's first Safari Zone events. Players who stop by the malls will receive an in-game medal and can find special Eggs from the various PokeStops located at the venues. They'll also be able to catch some of the game's rarer monsters, including Kangaskhan, Chansey, Larvitar, and even shiny Pikachu and Magikarp, among others. However, Niantic says that Gym and Raid Battles will not be available during the event "in order to optimize the experience for all Trainers attending."
