Earth Defender is not really the game that will impress you with the graphics that it has. Indeed, they are three dimensional and building the models tkaes much more time than with two dimensional objects, but the textures are kept at a basic levels and especially the color of the HUD was not chosen too good.
There are quite a few controls that you can use in order to steer your ship and use different weapons and you will have to give your best because the aliens are invading the planet and you will have to destroy all of their ships.
