This game can be used to train your eye-hand coordination and typing speed.
Alpha bombs are actually aliens from outer space trying to destroy planet earth. They can be destroyed by typing the letters or number found on them. There are a variation of aliens...
First, the grunts, they are the most stupid but can be deadly when they come in packs. Second, rotators, its rotates and make it harder for you to see their letters. Third, the critters, they eat through your defense! Fifth, the zeppelins, they drop saw blades, so kill them asap. Last is the Death Saucer, it will shoot out death ray over your city. BEWARE!
Can you save the planet from the alpha bombs? Defeat the threat before our cities are destroyed!
