Summary
Horizon Wars: Zero Dark is a miniatures agnostic skirmish game that can be played solo. The game doesn’t have a round structure, per se. What happens is that you take an action with one of your heroes, and then you flip a card.
The game has rules for either 1 off play or campaign style with XP and leveling. The card value determines what enemy activates (number cards for grunts) and the action they will take. The game can be played with pretty much any miniatures you have on hand.
The game is designed to be played by a team of up to four people. The rules are laid out in such a way that each player can choose their own character. There are no rules for the game, just a set of rules for each player. The game can be played in any order you choose.
