暮光帝国（第四版）是一场银河征服游戏，其中三到六名玩家扮演十七个派系之一，通过军事力量，政治机动和经济谈判争夺银河统治之一。每个派系都提供了完全不同的游戏体验，从蠕虫幽灵克里斯岛到哈桑酋长国，贸易和经济学硕士。这十七场比赛为胜利提供了许多途径，但只有一个可以坐在梅卡托雷克斯王位上，作为星系的新主人。

没有两个暮光帝国的游戏是一样的。在每个银河时代的开始，游戏一个板子是独特的和战略性的建造使用51个星系瓦片，其特点从繁茂的新行星和超新星到小行星和重力裂谷。玩家被处理在这些瓦片的手中，轮流在梅卡托尔雷克斯（Mecatol Rex）周围创造出星系，这是坐在董事会中心的首都行星。离子风暴可能会阻止您的种族进入银河系，而偶然放置的重力裂缝可能会使您免受最近的敌人的伤害。星系是你的工匠和主宰。

Twilight Imperium (Fourth Edition) is a game of galactic conquest in which three to six players take on the role of one of seventeen factions vying for galactic domination through military might, political maneuvering, and economic bargaining. Every faction offers a completely different play experience, from the wormhole-hopping Ghosts of Creuss to the Emirates of Hacan, masters of trade and economics. These seventeen races are offered many paths to victory, but only one may sit upon the throne of Mecatol Rex as the new masters of the galaxy.

No two games of Twilight Imperium are ever identical. At the start of each galactic age, the game a board is uniquely and strategically constructed using 51 galaxy tiles that feature everything from lush new planets and supernovas to asteroid fields and gravity rifts. Players are dealt a hand of these tiles and take turns creating the galaxy around Mecatol Rex, the capital planet seated in the center of the board. An ion storm may block your race from progressing through the galaxy while a fortuitously placed gravity rift may protect you from your closest foes. The galaxy is yours to both craft and dominate.
