Cry Havoc: Aftermath expands Cry Havoc with new skills and structures to add even more re-playability to the game. Each faction receives five new skills and three new structures, which nearly doubles the amount of unique abilities in the game.

Additionally, this expansion introduces an alternate game mode that ensures each game lasts for five full rounds. When passing an event token, instead of removing it, new scoring abilities are introduced that allow players even more options to gain victory points.
