Hidden Leaders: Forgotten Legends

From BFF Games:

Four unknown descendants of the Emperor have deciphered the forgotten legends and called upon the powerful guardian spirits of Oshra. Their ritual unearthed new treasures but also brought greed into the hearts of many. Will the new guardian leaders take over the land, or will the established powers prevail?

This expansion for Hidden Leaders comes with 3 new modules:

• A new faction, four leaders, and 20 new heroes. The guardians are a powerful race. Everyone can use them, but use them sparingly or you might make the Guardian Leaders win. This adds a new layer of deduction, a new winning condition and many powerful new abilities to the game.
• Artifacts will upgrade your leader character. Each artifact gives the respective player a unique ability that can be used 2-3 times during the game. This gives every player a unique play style and exclusive strategic options.
• A bag full of nasty corruption tokens. Two times during the game, a wave of corruption allows you to secretly change the alliance of your heroes or the heroes of your friends. But be careful: some of these changes are dangerous traps that players can use to protect their heroes from attacks of their friends.

The base game Hidden Leaders is required to play.
