Hordes of little aliens attack in swarms as you fly through those ominously dark clouds. Great feeling of flying here as they whizz past your ship.

Pressing the 'spread' button shoots the shield orbs outwards destroying everything they touch..but leaving your ship unguarded. Best saved for the nastier bad guys...

More bio-metallic aliens take pot shots at you.. The bad guys get meaner looking as you progress..check out the gnashers on those spaceships..

..until you reach the end-of-level boss which de-cloaks right in front of your very eyes.. Klingon technology anyone?

Best use your shield extensively here (unlike I seem to be doing..) Mind the laser beam it shoots from the front though, your shield orbs won't stop it.

Not too hard though, and the boss makes an exit even more impressive than his entrance when you finish him off..
