In Crimson Sun, players take on the role of leaders of Upper and Lower Egypt. Playing units of four unique gods (Kuk, Babi, Horus, and Sekmet), players build their forces and attempt to assert influence over four key structures. Players may choose to either draft decks at the beginning of the game, or use a single deck. During the game, players use the Unit cards in a variety of ways to increase his overall strength, to use special abilities, or to secretly try to gain control over the structures. The core mechanisms of this game are pulled from a previous Small Box Games' release — Bhazum — but mechanical and thematic changes have led to a game that should be a fresh experience for players already familiar with that game.
