Defiant is a 2D Space Shooter which challenges users to get the highest score possible so that they can compare their score to their Facebook friends one. In order to get the best score possible, you will have to survive on Asgar to all the enemies that may appear.
There are lots of enemies that you can encounter during the gameplay, and you will have to defeat them all to get a high score and maybe the first position on the Facebook friends ranking.
On Defiant, you can even buy more spaceships that have enormous power and a huge difference with the default one. Once we have bought a spaceship, we can modify it by buying some of the mods that are available on Defiant. Each mod has its specifications and can improve your gameplay and overall score.
