Better Dead Than Alien!

Your mission is to wipe out Alien waves as they appear in the battle zone. Be prepared to face all manner of unearthly beings. Some may be easily destroyed - do not be deceived, those that come after can be stubborn and lethal. But do no fear, help is at hand. You can win devastating extra battle powers and, during Master Alien waves, the freedom to move over the entire battle zone.
An Alien is at its weakest when its eyes glow a putrid green. Blast a greeny and it will release a power capsule which can be picked up by your ship. The power Capsule can recharge your Power Bars or, if one of the panel icons is flashing, boost your fire power with the indicated Destructivity Intensifier as depicted in Fig 3. Normally, any enhanced fire power you gain will be exhausted by the end of the current wave. Blast the last greeny in a wave however and the power so attained will carry through into the next.
