Imperium: 3rd Millennium is a board game released in 2001 for 2 players, 30–120 minutes per game, and ages 12 and up. It was designed by Marc W. Miller and its main mechanics are Hexagon Grid.
This is the long awaited re-release of Marc Miller's classic game Imperium, 3rd Millennium. This is a two player Hex and Counter game where one player plays the Vilani Empire that is slowly expanding to take over the entire galaxy. Naturally, the Vilani Empire has recently discovered the Terran Empire (Player 2) and conflicts arise for control of Earth and her surrounding star systems. This beautifully reproduced game comes with 330 counters, charts and tables. Three large maps of the star systems and jump routes, tactical planetary maps and 3-D space combat maps allow for many levels of strategic and/or tactical combat play. A small scenario booklet also provides a variety of scenarios to choose from. Re-implements: Imperium
