Unless you're completely brainless, you should already
know what type of game this is from the title!
for the really thick ones (like JR), this is a shoot
em up of the semi-3D variety where things come 'out'
from the screen towards you. You have to blast them
before they blast you, y'know a sort of kill-or-be-killed
game is presented as a view through the screen type,
complete with a Missile Command type cursor that
you aim for firing. You can also move left and right,
which helps you chase ships moving across the screen.
ship is in constant need of supplies, all three; ammo,
fuel and shields. These can be replenished by shooting
the object connected to the supply when it appears on
aliens themselves appear in front of you can proceed
to hurl boxes at your screen; if the boxes touch the
screen then you'll lose part of your shields.
have a set number of aliens to destroy per wave, although
some of them are 'humourous' and should be quite familiar,
Uncle Clive for example. Once you've destroyed all the
aliens on that wave then you progress to another, harder
action takes place over several types of smoothly scrolling
landscape, from mountain ranges to what looks like the
walls from Hunchback.
