Shooter from Oriental soft, heavy influence from XII Stag
as well as Trizeal. Three weapons may be carried and their
power controlled by picking up capsules of a specific colour.

Three capsule types:
. Red   - Vulcan
. Green - Missiles
. Blue  - Laser

Points are awarded by picking up medals which are released
from shot down enemies. The medal value and appearance is
increased as long as you don't miss any.

When enough medals have been picked up a "void" bomb becomes
available which when released (hold down main shot) will create
a circular "void". Enemy bullets which hit this "void" are transformed
into medals. If you place your ship inside this "void" it becomes
invulnerable like in XII Stag.

The game is powered by a HyperStone E1-32XT. A battery on the PCB
saves hi-scores. Hi-Scores can be reset by toggling switch S2.
