You play the game with the joystick and two buttons. The first button fires your normal weapon and the second fires your suped-up special weapon. These weapon are slightly different for each of the gazillions! of avatars you can choose from to start the game. The super weapon can only be fired when the power gauge at the bottom left of the screen is at least half full. Fire it, and you destroy everything in its path, but you lose the equivalent of half a power gauge. Thus, if you have a full power gauge, you can shoot your special weapon twice before your power is empty. Luckily, you are always replenishing your power.
Every 5 stages or so, there is a boss (check out the pic) who takes a while to conquer. Luckily, when you hit him with your regular shot, he releases goodies including "P"s, thus enabling you to power up your super weapon to finish him off.
The action isn't completely crazy and the cartoonish graphics definitely give the game a light feel - so overall the game doesn't have the intensity of some of the previous GOTDs. That being said, something about Ultraman Club keeps you coming back for more.
