Sector Strike!

They came from nowhere.

Without warning a series of portals opened up - threatening to swallow Earth's most distant colonies.

Humanity's greatest minds conceived of a massive grid large enough to span the solar system.

You must position the fleet's most powerful ship and launch plasma bolts across the grid, in order to close these portals.

Beware the aliens will soon detect your presence and try to block you.

Made in Z80 assembly for the ZX Spectrum 48k.
