On the war-torn battlefields of Trederra, legions of alien soldiers patrol the ruins of their once great cities, searching for anyone foolhardy enough to intrude into their territory. Waging war on each other for generations, the battle-scarred Nations of Trederra use Dark Stone to fuel their engines of death, polluting their planet with radiation and drifting clouds of toxic gas. But there are also treasures to be found amidst the devastation, weapons and technology advanced beyond reckoning by brutal centuries of warfare.

The Trederra Deluxe Expansion introduces a brand new OtherWorld for the Heroes to explore! This includes a full set of 18 new Map Tiles depicting the war-torn planet of Trederra, with dangerous new Radioactive Spaces and Cover Terrain! These Map Tiles also have an all new set of unique Mine rooms on the reverse, bringing more variety and new Encounters to discover throughout the Mines. All of the cards needed for this alien world are included, such as Trederran Encounters, Artifacts, Map Cards, OtherWorld Threats, and more, as well as a host of new cards for adventuring in the Mines! 6 New Missions will challenge your Heroes as well.
