Peacemakers: Horrors of War is a thematic co-operative board game where you attempt to bring peace. The game can be played with up to 4 players, including solo. As an adventurer, you try to stop armed conflicts between animalfolk nations. Do your best to avoid the horrors a destructive war would inflict.

The armies in the game act independently, so you cannot control them directly. Instead, you get multi-use resource cards, which you can use to thwart their plans. You only get a few new cards each round, so you have to figure out when and how to make the best use of them.
