Containers (boxes) are items from the warehouse that you open to receive a random reward: resources, fleet units, parts, or artifacts. There are seven containers in total in the game. Below is a breakdown of how they work and what’s inside each one. All data is taken from the game’s code.

Source of the data. The names, contents, and drop mechanics are taken directly from the game engine (the War of Alliances universe). The cards for each container can be found in the Containers section of the encyclopedia.

How Containers Work

  • They're sitting in the warehouse and piling up. The containers you receive are kept in stock; you can keep a few on hand.
  • Opening a container uses up one container. Once opened, one is deducted. If none are available, it cannot be opened.
  • Containers do not have inventory levels. They are either in stock or out of stock.
  • Up to 5 different rewards per opening. You can't get more than five at a time.
  • Drops are random and occur in "runs." Each container has several "runs"—the game rolls a chance for each one, and if it succeeds, a reward group is unlocked. The rarer the group, the more valuable it is and the better the potential rewards.

What Types of Containers Are There?

The seven containers are divided into three types: “Arsenal” (purchased), mission-based, and special.

Secret ContainerAll resources and the fleets of all three classes (light, medium, heavy)For viewing ads after the expedition

In the game, the Barbarians, Pirates, and Ravagers containers are grouped under “Arsenal”—they provide parts and blueprints for upgrading Arsenal.

New User Bonus

As long as you've opened fewer than 10 containers, the Secret Container is guaranteed to contain at least 1 Antimatter—it's a safety net for beginners to ensure that your first few openings are definitely worthwhile.

How to Get Containers

  • Arsenal Units (Barbarians / Pirates / Ravagers) — can be purchased with resources (Dark Matter or Star Ore).
  • Small / Medium / Large — awarded for completing daily, weekly, and monthly missions (Medium is also awarded for tournaments).
  • Secret — a reward for watching a short commercial after an expedition flight.

Frequently Asked Questions

Is it possible to know in advance what will come up? That's right—no, the reward is random. But the contents of each container are known (see the table above): the reward is selected from this set.

How many awards does a single discovery yield? Up to five different items at a time.

Are the containers piling up? Yes, you can keep a few in stock and open them whenever it's convenient.

Where can I see the contents of each container? In the Containers section of the encyclopedia and directly in the game when you open it.
