aliens are here in
vast inter galactic mining ships to "EAT" our solar system.
They are after resources :- base metals, heavy gases, complex
carbons, liquid hydrogen, etc. In fact exactly the sort of stuff that
the planets in our solar system are made of!
must defend each
planet in turn. Don't let the aliens land 3 ships on a planet, that's
all they need to set up a focused singularity point explosion to blow
the planet into obliteration and harvest the lumps.
have a high powered
dark matter laser in low orbit, just tap on the screen to aim and
shoot the invaders. Unfortunately the laser only works in space so
cannot be used to kill any invaders that have already landed, if
three ships make it to the surface its bye bye planet and game over!
