Take Civilization 6, with its strategic city building and decision making as you expand your empire across a hex-based map while outsmarting your rival factions. Add Slay the Spire, with its card-based tactics, asking you to build a deck capable of consistently delivering the tools you need to secure victory. Now shake those up and pour over ice, and you get Hexarchy, a cool 4X deck builder coming to Steam in October. Ahead of its release, PCGamesN spoke to developer Main Tank Software at WASD to find out what makes it tick.
