History:

Ten months ago, 5 Giant Robots in the shape of excavators arrived on earth and unearthed a virus that is very contagious and deadly for humanity. Millions died from the pandemic and more from robot missile attacks. Humanity built a giant machine to fight them called Birdon, your mission is to destroy the robots and not let them destroy the only laboratory that remains to generate the vaccine that saves human beings.

How to play:

Your mission is to protect that the giant robots do not destroy the vaccine laboratory, therefore you must go with Birdon towards them and shoot until you destroy them avoiding their missiles. Sometimes an invincibility mode is activated where you will see Birdon blink and you will see weak points in the robots that will allow you to destroy them faster. When some of the robots arrive near the laboratory, an alarm is activated, they stop in front and begin their attack, on the fifth impact the laboratory is destroyed and the game is over. Get the most points and share your achievement in the world High Score table.
