XR City - ロストアニマルプラネット　AR恐竜ゲーム is a free iPhone game developed by NTT QONOQ INC. In this game, set in a world on the brink of the sixth great extinction, you play as a Lost Animal Hunter and your mission is to gather data to revive extinct dinosaurs and animals to prevent the mass extinction.

The game features two main gameplay modes. In the "Excavation Challenge" mode, you can collect fossils to revive extinct creatures. The higher your score, the more chances you have to collect a large number of fossils. In the "Field Excavation" mode, you can encounter rare extinct creatures and dinosaurs that can only be found in specific locations through special AR effects.

You can register the collected extinct creatures and dinosaurs in the encyclopedia, where you can view detailed information about their habitats and behaviors. As you collect more creatures, you earn research points that increase your research level and unlock more detailed information. Additionally, you can use the app's observation mode to bring the revived extinct creatures and dinosaurs to life in the real world through augmented reality (AR) technology. You can take AR photos and videos, and share them with others.
