Perfect 3D arcade game. 100 levels, dashing fight, excellent
graphic, incredible sound tracks.
...A Dark time for the Human race has come. The Earth is in danger.
Aliens are going to capture planet Earth (as they always are).
It's clear to see that they are ugly, loathsome, vile and have the
worst designs of all conquerers. Women will be eaten away, the
brains of intelligent men will be worked into liquid assigned to
wash their nasty spaceships, children will be taken away for
terrible experiments. The others will not be spared, obviously
they will be simply pulverized into dust. So, there is a need for
somebody to save humankind.

The Aliens have settled over Earth and are now in orbit. In
response Earthlings quickly build an armed spaceship and equip an
expedition to give battle. It becomes known that the alien energy
is contained in crystals scattered all around the Arcadrome (their
vehicle launching site). The only way to neutralize their hordes
is to capture all crystals and to leave the enemy without energy.
That is the last hope of humanity. The spaceship is cramped, and
only one man can go in (may be bad since calculated in a hurry).
And you have been selected as that one man. Your civilization is
gazing up to you as their sole hope for survival.

"Out of everybody trying to save our planet Earth you are the
selected one", said the President grimly at parting, his face
grave with concern...

Your goal is to pickup all the crystals scattered over the field.
There are many monsters in Arcadrome, each one has its own tactics to
prevent you from completing your noble work. Some of them represent a serious danger.
They can shoot at you, mine the field ahead of you, steal your
crystals and so on. Be careful of meeting your unknown foe.
