Osprey Games announced Imperium: Horizons, a standalone deck-building game, for release in summer 2023.

Imperium: Horizons continues the Imperium series of asymmetric deck-building games that began with Imperium: Classics and Imperium: Legends (see "'Imperium' Card Games"). This new standalone adds 14 civilizations to the mix, which are fully compatible with the first two games. It also features a new trade module that lets players compete over wealth and the dynamics involved with a booming economy.

The game box comes with more than 550 cards and over 150 tokens. This new game is for one to four players, ages 14 and up, and plays in 40 minutes.
