In Helios you are being attacked by Thanatos, the god of death. He is sending his spiky little minions to defeat you. All you have is this little arm that throws powerful balls of life to defend yourself. How will you do it? You'll click the mouse and hold it down to grab a ball, and then "throw" the ball and release the mouse at the point you want to throw it. You can earn money and buy upgrades to your balls in the shop between each level and there are numerous badges to earn as well. See if you can get through all the levels and finish the campaign in Helios!
