Mission Cobra (also known as Sidewinder in Australia and Asia) is a 1989 action arcade game developed by Joy Van and published in Australia by HES Interactive and in Brazil by Milmar.
The player's life consists of an "Exx" counter.
This will be drained constantly when flying and a large amount will be lost if hit by enemy fire.
When an enemy vehicle is destroyed they leave power-ups and some refill the "Exx" counter.
There are three levels in the game and they all end with a boss fight.
