Defend the core with your shield and survive as long as you can!
Rotron is a fast paced arcade game which demands quick reactions. Destroy the bad orbs, let through the good ones. How long can YOU withstand the bombardment?
If red orbs hit your core they can destroy your shield, diminish your health or increase the game speed. They can even unleash Armageddon. But with quick movements, green orbs and a bit of luck you might survive just long enough to be the best of the best!
