Air drop chest

The air drop chest works somewhat differently from regular chests. It is obtained by spending reinforcement points that you get from the "Friendly assistance" feature; when you buy one of these chests, it opens immediately without any waiting in a queue. You can also buy more than one air drop chest at a time if you have enough reinforcement points available. The rewards aren't huge, but they're free!
