DRONE DUSTERSBY BOB AYIK   Drone Dusters is a fast andfurious machine language game basedon the tank-action arcade hit Targ.To complete one of the game's 15screens, you must run over all 13pulsating dots or shoot all ninepursuing drones that are trying torun over you.   You can play Drone Dusters with ajoystick or from the keyboard.  Plugthe joystick into port 1.  First,copy DRONE.EXE to another disk whichhas the DOS.SYS and DUP.SYS files onit.XXX  Next, rename DRONE.EXE toAUTORUN.SYS.  Now turn off your Atariand place this disk in your drive.Remove any cartridges (XL/XE ownershold down the [OPTION] key) and turnon your Atari.  Drone Dusters willload and run automatically.   Each of the first eight screensadds a pre-set group of blocks to thegrid.  But the last seven screens addblocks randomly.  Display colors alsochange at each new screen, so it'srare that you'll see the same screentwice during a game.XXX   If you prefer not to play with thejoystick, keyboard moves are asfollows.  To go left, press [S]].  Togo right, press [D].  Up is [U] anddown is [N].  Pressing [CONTROL] [Q]aborts the game and takes you back tothe title screen.  Pressing [ESC]takes you back to DOS.  To playanother game, press the joystickbutton or any key and then press[START].   Your tank consists of twosuperimposed players, with adifferent design for each of the fourdirections it can face.  You can movein reverse at any time, and you can"turn a corner" before reaching itXXXsimply by pushing the joystick or akey for the turn.  When the tankreaches the first corner in thatdirection, it will turn toward it.Be aware, however, that the tanklikes to keep moving -- YOU must findout how to stop it.   The nine drones are bit-mappedGraphics 1 characters requiring 15redefined characters for eachdirection a drone can face.  Dronespeed increases with every fourthscreen, as well as when five or onedrones are left on a screen (afterthe first two screens).  Maximumdrone speed is never faster than thetank.XXX   When you get to the fourth screen,you'll start seeing a UFO -- arotating triangular object.  As theUFO movement speeds up, so does itsspin rate.  It will appear in acorner of the grid and flash briefly,taunting you to shoot it.  And whenyou do blast it apart, it willreappear shortly thereafter and movefaster.  But it will never get fasterthan your tank.  The UFO chases thetank with a "smarter" algorithm thanthe drones, and it constantly firesbullets at the tank, so keep on yourtoes.XXX   Each drone you shoot is worth 35points.  Running over a dot gets you25.  Shooting down a UFO is worth 95points.  You'll earn 1,000 points foreach screen you complete, up to 9,000points.  At 20,000 points you'll getan extra tank.
