When two Purge the Foe armies meet, both players are dealt Meatgrinder.
Purge-the-Foe mirror. Destroying any enemy unit pays at end of turn. From the second battle round, non-home control pays at the end of your Command phase, while end of turn pays separately for out-killing the opponent (more enemy units destroyed this turn than friendly units lost last turn) and for holding their home objective.
Primary scoring is capped at 15 victory points in a battle round and 45 across the game.
