There will be 2 types of Random Rewards: small and large. The first four rewards you earn will be small and the fifth will be large and of course, the contents of a large reward will be more valuable.
Pay attention: Random Rewards do not accumulate and open immediately upon receipt (at the end of a battle).
Now for the exciting part - what are these Blueprints we are offering? Let’s dig into the details.
Blueprints
Please note: This is a brief overview. A dedicated article will be coming soon, going into more detail on this new feature.
Blueprints are special content items that you can get from Random Rewards and can be used to get discounts when you research new tanks.
The higher the vehicle Tier, the more Blueprints it’s made up of and with every Blueprint you receive, your discount grows. This means if you collect every single Blueprint of a specific tank, you will receive a 100% XP discount on the research cost of the vehicle.
NOTE: Blueprints can only be obtained from Random Rewards. They are not purchasable for Credits, Gold or real money.
You don’t have to collect all the Blueprints to take advantage of them, but the more you have, the bigger the discount you will receive.
Blueprints will drop at random and are available for vehicles of all branches and nations from Tier II to Tier X, including vehicles that you have already researched. To make it easier for you to track the number of collected Blueprints, we'll introduce special progress bars, divided into sections. After receiving a Blueprint, one of the respective sections will be filled in.
If you get a Blueprint for a vehicle, which you have either researched or have all the necessary Blueprints already, it will turn into a “national” or a “universal” Blueprint. National Blueprints can be used on any vehicle of a their respective nation (for example, if you receive a national Blueprint for France, it can be used on any vehicle in the French tech tree), while universal Blueprints can be used on any vehicle of any nation.
Please note: you can convert only "national" and "universal" Blueprints, but Blueprints that you already have for a specific tank cannot be converted. You may find out that you already have a discount for some vehicles right in your Research tab.
