• Parts: these allow you to improve planes that you own. Each plane has specific parts, which can only be used to upgrade technologies for that plane. Parts can be obtained from opening crates, as rewards for progressing in events, or purchased in the in-game store. Most sources provide random parts for all planes you have unlocked. In some cases, like specific event rewards or in-game store offers, parts may be dedicated to a certain plane. In such cases, it will always be specified in the reward or offer description.
    Parts will let you upgrade technologies up to tier 2. In order to upgrade technologies further to tier 3, you’ll need Tokens.
  • Blueprints: a plane-specific resource that allows you to unlock new planes from reached tiers, and add them to your hangar. Each plane may require a different number of Blueprints to unlock. Blueprints can be obtained from various rewards in-game and from in-game store offers. Unless specified otherwise, all Blueprint sources provide resources for random planes.

  • Tokens: a special currency that lets you upgrade technologies above tier 2. Unlike Blueprints and Parts, Tokens can be used for all planes.
  • Silver: the basic WoH currency, used for various transactions. Most commonly used alongside Parts for plane upgrades. Silver can be obtained from various in-game rewards, crates, and the store.

  • Gold: a premium currency used for speeding up time-restricted activities, like opening crates. Found mainly in event rewards and the in-game store. It can also be used for some offers in the in-game store.
