Zems is a free-to-play collectible card game blended with turn-based, hex-based tactical battles.

Players may compose a deck using one or two colors from six available colors, each with their own specialty in combat. Battles take place on a hex-based grid, and utilize elements and weather effects created by the player to change and manipulate the battlefield. Battles can take place in Ranked and Unranked mode, with a Draft mode planned.
