A great vertical shoot'em up.
Players have to pilot a aircraft and shoot the alien waves space ships and dodge his attacks, while destroys a giant latticed ground structure, for this you must shoot first a special ship in mid-air to get the extra weapon and now you are ready to throwing bombs for destroy all the square targets, this makes the whole structure collapses in order to continue on to the next scene and later face off to the end boss structure.
