Bugs © 1982 Data Age, Incorporated.
You must destroy the swarms of invading bugs, out to immobilize your space craft, before they completely leave their nests. At the same time, you must be on constant guard against the Phylax oozing through the hull of your craft and bent on destroying your only weapon.
Each bug destroyed scores one point.
Destroying a Phylax scores five points.
After you score thirty points you advance automatically to a new skill level (indicated by a new Cosmic Barrier), scoring a bonus of eight additional points.
