Pokémon GO has been pushing more events to its users as its user base has begun to decline. The company today announced a new event in hopes that users return to the AR-based game.

The game notes that players will be able to find 2km Eggs, which will only be available throughout the event. “This means that Pokémon that normally hatch from 5 km or 10 km Eggs, such as Wynaut or Ralts, will be found in 2 km Eggs,” the company says. In addition, the company will also be increasing the hatch rate of certain Pokémon.

A few other companies are trying to mimic Pokémon GO’s AR-style gameplay. While ARKit was released alongside iOS 11, not many game developers have taken advantage of the technology just yet.
