Les forces spatiales des principales puissances de la Galaxie (Fédération, Klingons, Romuliens, Kzintis, Gorns, Tholiens, Orions, ...) se confrontent dans des combats spatiaux pour le contrôle d'une zone ou pour d'autres raisons stratégiques.
Il s'agit d'un jeu de combat de vaisseaux sur une carte hexagonale. Les joueurs commandent un ou plusieurs vaisseaux, gèrent l'énergie et décident des mouvements avant chaque tour. Les armes sont tirées durant le tour. Les vaisseaux disposent de boucliers et d'armures pour se protéger. Lorsqu'ils sont endommagés, les capacités de combat du vaisseau sont réduites.
De nombreux scénarios solo ou multijoueurs sont disponibles.
