Zoner PDA is developed specifically for Zone 37 airsoft role-playing events and brings a new level of immersion to airsoft events. Features: - Quests. Every player has individual faction quests and additional side quests issued by multiple NPCs. - Interactive map with POIs and quest markers. - Radioactive zones. The map has multiple radioactive zones, but they're not marked in advance. You can track your radiation accumulation in real time. - Emissions. The emission is accompanied by a notification and a siren, and it also displays a timer so you have time to take cover. - Rewards and balance. Rewards for completing quests are automatically credited to your balance the moment you complete the quest. You can use your balance for purchases from the Trader or your Commander, as well as withdraw physical coins at the Bank. - Quest Items. To confirm completion of certain quests or possession of specific quest items, you should scan quest items through the app. - Wiki. Here you will find information about in-game items and props. - Personal notifications. You can receive personalized real-time notifications — for example, alerts regarding bounties, out-of-game notifications, NPC invitations, and more. Recommendations: - We recommend the use of an external power bank for your phone. - Do not exit the app during the event. This way, you won't miss anything important and will get the most immersive experience. Warning! Zoner PDA is designed specifically for Zone 37 airsoft activities. You won't be able to use the application for anything else, such as casual navigation or tourist orientation. You won't be able to use the app without purchasing a ticket to one of our airsoft events. Please do not download the app if you do not intend to participate in our events.
