Crystal Age: Prototype Preview.

About Crystal Age, from BoardGameGeek:

Crystal Age is a fantasy board game for 1 to 4 players with an approximate duration of 30 minutes per player. It has three different game modes: solo, cooperative, and PVP. The corruption of the crystal spreads through the world. Become a Hero and collaborate with your allies to defeat it or fight against the other heroes and become the Lord of Corruption. In the past, a colossal crystal fell from the sky into the center of the land of Ansel, forming a huge crater. It began to corrupt the nearby biomes, and the creatures that lived there became more powerful and hostile. The kingdoms sealed the crater with 4 magical guardians, and surrounded it with a giant wall to prevent the spread of this strange disease, called corruption. You are a Hero graced with power from heaven and you feel the call of the crater.... Now tell me... Will you use your power to help end the corruption? Or will you submit to the greed and doom of being the most powerful hero of Ansel? Welcome to Crystal Age! —description from the publisher
