Your mission is to destroy all these alien matters before they fall over the city and make explosions. With every explosion the Danger level increases and it touches the maximum limit, the level fails and you have to play from the beginning. There are two types of alien matter falling in this Ben 10 game, • Fireballs – These are alien matter and when they touch the ground, it explodes. You can use the echo super power of Big Chill to destroy them or simply touch them and they will vanish. • Orbs – Orbs are much more dangerous than Fireballs. You can only destroy them with Echo superpower.
