Conquer all 15 cities by winning battles against machines built for war. Each battle plays a little bit like Rock Paper Scissors, with the machines having three modes: twister, hurricane, and earthquake. At the start of every turn, you and your opponent must choose one of these modes. The player that picks the advantageous mode will attack while the other player defends. Machines have different sets of power-ups for each outcome (attack, defend, and draw). Click on a power-up before the timer expires to use it. Using power-ups depletes your machine's energy. At the end of each turn (3 rounds), you can choose to recharge your energy or repair your machine. The player that pushes the opposing machine off the cliff wins the battle. Buy and equip power-ups between battles to increase your chances of winning.
