Based on the card game "War", but with a twist. Take part in the epic battle between gun-toting kitties and power-hungry aliens. If you have ever played the game of "War", then No Mercy will be instantly familiar. "No Mercy" follows the same game mechanics, in which each player turns over the top card of their deck, and the player with the highest card wins. But there is a twist: the player with the lowest number has the option to pull the facedown card from the top of the modifier deck; modifiers can add or take away from your card's number, and can also be an action that has a positive or negative result on your hand. As with war, the winner is the first person to lose all their cards, or, optionally, the player with the largest deck when a time limit is reached. Each card contains an imaginative drawing by the children's book illustrator and comic artist Travis Hanson.
