Alie  blockade  will be familiar to fans of  the  arcade 
     game Qix,  where the objective is to trap analien in a  small 
     portion  of  the  screen.   Written  in  machine  code,  with 
     fantastic  background pictures,  this game will  soon  become 
     very popular in the public domaine game world.

          You begin with a border around the whole screen,  around 
     which  you can move a small cursor.  Drawing lines  from  one 
     section of the border to another will devide the playing area 
     into  two sections.  The smallest of these is filled in  with 
     part  of  a picture,  altering the shape of  the  border  and 
     redusing the area the alien has to roam about.

          To complete each level you'll have to keep drawing lines 
     untill the playing area is reduced to such a small size  that 
     the alien can't move very far.

          If  the  alien  hits you or touches  the  line  you  are 
     drawing, you'll lose one of your three lives.

          At  the bottom of the screen is a timer,  and when  this 
     runs out you'll lose another life.

          The game becomes even tougher on the later levels,  when 
     in  adition to the alien there are Tracers which  move  along 
     the  border of the playing area.  If they catch  you  another 
     life goes down the drain.

          The game is joystick controlled and pressing fire  while 
     moving will draw a line.  If you manage to trap the alien  or 
     one  of the tracers in the smaller,  you‚ll be awarded  bonus 
     points  and  the baddie will be transfered to  the  remaining 
     area.

          Should  you  manage to reach 10.000  points,  you'll  be 
     given  an  extra life,  but don't think this is going  to  be 
     easy.

          For  such a simple idea,  this has got to be one of  the 
     most addictive games ever written.
