Proton Defence

 

 

 

THE PLOT

 

The Anti-Matter War has just begun…

Coming from nowhere, hordes of anti-matter aliens are attacking our Galaxy.

 

Anti-Matter?

 

Right, their atoms are made of anti-particles: positrons, anti-neutrons and anti-protons.

The humanity has always wanted to know whether the universe will be ever expanding,
or will finally retract due to its own mass, leading to another Big Bang…

Now the truth is that we are doomed to return to pure energy sooner than expected,
because any contact with those anti-matter aliens results in complete annihilation
(more exactly, the alien mass and yours will be converted to pure energy,
following the famous E=mc² formula)

 

There can be no winner in this war, not even a Pyrrhus victory…

 

 

THE CHARACTERS

 

So, why are those aliens rushing to us in such a kamikaze way?

They are doomed to have every of their particle annihilated when touching the Earth,

No one knows, every tentative of approach has finished in a big explosion…

It just seems they are completely frenzy, just look how they jerk when descending!

 

 

After the impact of the first scout alien, our scientists have devised a simple
but effective weapon: proton bullets.

Proton guns were already praised in the 27th century for their kinetic effects,
and now that we know how to make high-density proton bullets,
it was just a question of firing the right number of protons
so that it balances the mass of those deadly aliens.

You are thus in charge of the three spaceships that form the last barrier
before Earth destruction:

The Proton Defence

 

 

So, blast those deadly aliens with your Proton Defence spaceships before
they reach the ground.

Fortunately, the mass of our planet is much larger than the one of these aliens,
missing one alien doesn’t mean the end of the humanity.

But the aliens have the same level of technology than us and have thus
designed a high-density antimatter Admiral SpaceShip,
that you must absolutely destroy before it reaches the ground surface.

 

 

 

TECHNICAL INFORMATION

 

 

As if it wasn’t enough, you will notice that the aliens spend some time in charging columns:
they drop their positrons there just to make even more damage on the ground surface.

 

 

Actually, this is quite clever of them, because they are then negatively charged
(remember anti-protons are negative particles)
and thus their impact on the ground surface will destroy the protons of our beloved atoms,
leaving plenty of electrons alone that are attracted by your massive amount of proton bullets.
As a result, a part of your proton bullets will pair with these electrons,
vanishing in the form of hydrogen gas, as you will notice from the energy bar
on the right of the screen (it will go from the green optimal level to the critical red level).

 

Did I say the screen?

 

Yeap, fortunately you are not inside the Proton Defence spaceships,
you control them remotely from an Oric Atmos computer,
the one and only computer that has proved reliable enough to cross the two latest Milleniums.

Despite its lack of sprites, it features a powerful 1 MHz 6502 processor,
which will smoothly render all these jerky aliens on your high-resolution screen,
and even give you an audio feedback of the stressful impacts.
Add to this an excellent keyboard with left and right keys to comfortably control the spaceships
and a robust space bar that you can punch to blast these aliens, and you will agree
it was worth preserving the Oric for the sake of the humanity.

Last but not least, a time travel feature has been added in software, just
in case you should fail with your mission: in such a case, just press
the space bar to switch back to the beginning of the Anti-Matter War (great computer, indeed).
