For those who aren't too familiar with this game, Warlords is a remake of the four-player arcade game (original poster pictured at right) which played like a weird combination of Breakout (Arkanoid for you NES and DS players) and QuadraPong.
In Warlords, four players have to defend their base or castle (located in one of the four corners of the screen) from a bouncing ball using a single flipper or shield.
Each player's base is surrounded by bricks which can only take so many hits from the ball before it disappears. Once these bricks are gone, the center of the castle becomes exposed. One hit to the center and, to quote Hudson from the 1986 classic Aliens, "that's it man, game over man, game over."
Players aren't limited to simply bouncing the ball off their shield and hoping it hits an opponent's fort. Each person also has the ability to grab onto a ball using their paddle, take aim, and fire with the A button.
