DRONE DUSTERS›BY BOB AYIK››   Drone Dusters is a fast and›furious machine language game based›on the tank-action arcade hit Targ.›To complete one of the game's 15›screens, you must run over all 13›pulsating dots or shoot all nine›pursuing drones that are trying to›run over you.››   You can play Drone Dusters with a›joystick or from the keyboard.  Plug›the joystick into port 1.  First,›copy DRONE.EXE to another disk which›has the DOS.SYS and DUP.SYS files on›it.›XXX›  Next, rename DRONE.EXE to›AUTORUN.SYS.  Now turn off your Atari›and place this disk in your drive.›Remove any cartridges (XL/XE owners›hold down the [OPTION] key) and turn›on your Atari.  Drone Dusters will›load and run automatically.››   Each of the first eight screens›adds a pre-set group of blocks to the›grid.  But the last seven screens add›blocks randomly.  Display colors also›change at each new screen, so it's›rare that you'll see the same screen›twice during a game.›XXX›   If you prefer not to play with the›joystick, keyboard moves are as›follows.  To go left, press [S]].  To›go right, press [D].  Up is [U] and›down is [N].  Pressing [CONTROL] [Q]›aborts the game and takes you back to›the title screen.  Pressing [ESC]›takes you back to DOS.  To play›another game, press the joystick›button or any key and then press›[START].››   Your tank consists of two›superimposed players, with a›different design for each of the four›directions it can face.  You can move›in reverse at any time, and you can›"turn a corner" before reaching it›XXX›simply by pushing the joystick or a›key for the turn.  When the tank›reaches the first corner in that›direction, it will turn toward it.›Be aware, however, that the tank›likes to keep moving -- YOU must find›out how to stop it.››   The nine drones are bit-mapped›Graphics 1 characters requiring 15›redefined characters for each›direction a drone can face.  Drone›speed increases with every fourth›screen, as well as when five or one›drones are left on a screen (after›the first two screens).  Maximum›drone speed is never faster than the›tank.›XXX›   When you get to the fourth screen,›you'll start seeing a UFO -- a›rotating triangular object.  As the›UFO movement speeds up, so does its›spin rate.  It will appear in a›corner of the grid and flash briefly,›taunting you to shoot it.  And when›you do blast it apart, it will›reappear shortly thereafter and move›faster.  But it will never get faster›than your tank.  The UFO chases the›tank with a "smarter" algorithm than›the drones, and it constantly fires›bullets at the tank, so keep on your›toes.›XXX›   Each drone you shoot is worth 35›points.  Running over a dot gets you›25.  Shooting down a UFO is worth 95›points.  You'll earn 1,000 points for›each screen you complete, up to 9,000›points.  At 20,000 points you'll get›an extra tank.›
