Twilight Imperium: Fourth Edition – Thunder’s Edge

About this expansion

Twilight Imperium: Fourth Edition – Thunder’s Edge is a colossal expansion for 3–8 players, with play sessions lasting around 480 minutes. It brings the galaxy’s great struggle to a breaking point centered on the titular planet of Thunder’s Edge.

New factions enter the galactic stage, while new worlds offer opportunities to explore or exploit. The expansion adds fresh possibilities to the interstellar conflict and gives players more ways to shape the fate of the galaxy.

A suite of Galactic Events introduces modifiers that change the rules of the game. These shifting conditions help ensure that no two playthroughs of Thunder’s Edge are ever the same, creating a conflict that can evolve in unexpected ways from one game to the next.

• New factions join the struggle for galactic supremacy.
• New worlds expand the galaxy for players to explore or exploit.
• Galactic Events alter the rules and provide changing conditions.
• Twilight’s Fall offers an alternate way to play Twilight Imperium.

The expansion also introduces the brand-new Twilight’s Fall mode. In this alternate experience, you take on the mantle of a mad Mahact king, build a custom faction from the scraps of interstellar civilization, and battle to become the supreme ruler of the galaxy.

Twilight’s Fall includes its own spread of unique components, making it feel almost like an entirely new game. Released in 2025, Thunder’s Edge is built for players ready to face a galaxy on the edge of a blade.
