From the announcement:
In every game of Kharnage, you and up to three other players take command of fantasy armies, battling for dominance around a tiny hill. Your troops are drawn up in their lines of battle, and your only goal is to cause as much damage as possible—earning Kharnage tokens by destroying your opponent’s units.
But before you can slam into the enemy lines with a spine-tingling howl, you’ll need to select your strategy for the round from your available strategy cards. Every strategy card sets the stage for the rest of the round. The initiative value on the strategy card determines when you will take your turn, since players take their turns in initiative order, from lowest to highest. Your strategy card also determines exactly what you’ll be able to do on your turn. Reinforcement flags indicate how many new units you can add to your army by drawing cards from the top of your deck and slotting them into your battle lines. Beneath the reinforcement flags, you’ll see a number of attack symbols, which determine the types of attacks that you can make on your turn: melee, ranged, or magical attacks. What’s more, because every faction has its own unique set of strategy cards, playing as the Dwarves, for example, feels very different from taking command of the Goblins.
