Sinistar (SynaMax difficulty/titlescreen hack)

Your intergalactic crystal-mining mission takes you to the antipodes of the known universe. But your parametric DeepSpace scanner faithfully displays the sector of the galaxy you presently occupy (including an area fully three parsecs across, no less)!

Keep the galaxy safe for all its sinizens! Fiendish Worker ships from the planet Sporg will attempt to fabricate a Sinistar from the remains of derelict planetoids in your very sector. You must not let them do this for two reasons:

1) These planetoids contain the life-sustaining crystals that your civilization requires for its vital technologies.

2) With the eminently unstable Sinistar in their possession, the Sprogites can lay waste to any civilization in your sector. You alone stand in their way.

You must mine the sinisite crystals. Williams has equipped you with the latest heuristic electret cannon technology. All you need to do is aim at a planetoid and shoot. Now collect your motherlode!

In fact, only with sinisite can you manufacture sinibombs to eradicate the Sinistar. But you must also rebuff the Workers and disintegrate their even more aggressive comrades-at-arms, the evil skelomorphic Warriors! Intelligent beings everywhere depend on your courage, your dedication, your reserve, your shrewd command of tactical invention! It's up to you, space cadet!
