Edited sentence: However, while activated, they drain charge power and need to be used sparingly.Some weapons cancel each other out though, so a little experimentation is called for.The graphics are very Giger-esque (a popular style during the late 80's/early 90's) and none the worse for it, with some nicely drawn alien craft and fairly spectacular end-of-level bosses.The player also has a shield at his disposal, in the form of four spinning orbs that circle around the ship when the A button is pressed, and are retracted by pressing the button again.The price of all this graphic detail is that there is so much going on at certain points in the game, with swathes of bullets, explosions and FX, making it a little hard hard to keep track of the ship in the mayhem.These shield orbs can also be used as a smart bomb if called for, whereby they spin outwards destroying anything within their area, although the player is limited to using these only when the charge power is high.Using the shield orbs becomes mandatory at many stages of the game so, besides relying on any high degree of shooting skills, the best way to progress is to learn where and when to use the shields
