      HORUS/SAND WARRIORS INSTRUCTIONS                     3rd February 1996
      

      Horus accepts various parameters through the DOS command line. These
      parameters are the only way in which the player can select the various
      options at the moment.

      DOS Parameters
      
      /h /? /help              help option
      /mouse                   for mouse control
      /mouse=xx                mouse control and sensitivity (defaulft 80)
      /joy                     for analogue joystick control

      /night                   night time mission.
      /map=x                   map selected 0 to 6 (default=0) (not impl.)
      /depth=xx                landscape depth 20 to 32, default is variable
      /sky=high                sky detail high (default)
      /sky=low                 sky detail low
      /record="xxxxxxxx.xxx"   recorder mode on and file name
      /playback="xxxxxxxx.xxx" playback mode on and file name

      Examples
      
      To run Horus using the mouse in VGA type:
      HORUS /VGA /MOUSE

      to run Horus using the joystick in SVGA with minimum depth type:
      HORUS /SVGA /JOY /DEPTH=20

      to watch a pre-recorded Horus file called 'DEMO.REC' type:
      HORUS /PLAYBACK='DEMO.REC'

      typing just HORUS the default values are used.


      About the Super VGA Mode Option
      
      The SVGA mode supported is 640x480 in 256 colours. This mode was chosen
      because it is widely supported by all SVGA cards. Speed wise, the
      program runs at half the speed when this mode is selected. There is an
      extra option of low definition graphics in this mode (fat pixels) which
      is faster than the full hires mode but the quality is not as good, but
      still better than VGA mode. To run the program in SVGA type:
      HORUS /SVGA
      and to run it in low definition SVGA type:
      HORUS /SVGA /LOW






      Controls
      
      The joystick controls have been coded and can be chosen by typing:
      HORUS /JOY. The keyboard controls have not been programmed yet. Please
      use the joystick controls at the moment to get a feel of the flying
      model. The mouse can also be used but it is not as easy to control as
      the joystick. To use the mouse type: HORUS /MOUSE. If you find that the
      sensitivity of the mouse is too much or not enough, it can be changed
      by typing: HORUS /MOUSE=50 which means 50% sensitivity. Any value
      between 0 to 100 is valid. The default sensitivity is 80%.

      Frame Rate
      
      The /DEPTH=xx and /SKY=HIGH or /SKY=LOW options are detail levels which
      are used to ensure that the frame rate is about right on any PC. To
      achieve maximum frame rate type: HORUS /DEPTH=20 /SKY=LOW
      But for maximum detail type:     HORUS /DEPTH=32 /SKY=HIGH
      If no parameters are passed then the program checks the speed of the
      processor and selects a suitable detail level.

      Pre-recorded Demos
      
      A pre-recorded demo file which can be played back using the /PLAYBACK
      parameter. For example to watch the recording called DEMO.REC type:
      HORUS /PLAYBACK="DEMO.REC". This will load and play the demo file.
      No control option is needed because the REC file keeps all
      the relevant information. You can run a demo in SVGA by adding the
      /SVGA switch eg: HORUS /PLAYBACK="DEMO.REC" /SVGA. To exit a demo
      simply press ESCape on the keyboard.

      It is possible to make your own recordings by using the /RECORD option.
      Assuming that you want to make a demonstration of the program called
      DEMO2.REC (any valid DOS file name can be used) using the joystick, you
      should type: HORUS /RECORD="DEMO2.REC" /JOY. Press ESCape to stop the
      recording and exit to DOS.

      NOTE: When the program is in record or playback mode, all collisions
            with the landscape are disabled at the moment.

      Day or Night
      
      By default the game runs in the "day time". This can be exclusively
      requested by using the option /DAY . Alternatively, night time can be
      selected by selecting the option /NIGHT .

      SPEED CONTROLS
      

      Maximum Speed
      
      By pressing the 'Enter' key the craft accelerates to maximum speed.
      At this high speed all flight controls on the craft are manual. Any
      collision on the landscape results in damage to the aircraft.

      Safe Speed
      
      The 'Back-space' key puts the aircraft on safe speed level. This is
      approximately half maximum speed. The advantage of this is that the
      craft's automatic systems can overide manual controls (when in danger
      of a collision) and avoid any damage to the craft. Flying at any speed
      below the 'Safe Speed Level' is also 100% safe.

      Auxiliary Thrusters
      
      These can be activated in normal flight and at any speed, in order to
      deviate the aircraft from its course at a variable degree. The 'CTRL'
      key or button 2 on the joystick/mouse can be used in conjuction with
      directional movement.

      Afterburners
      
      The 'Tab' key activates the afterburners. This gives a very powerful
      momentary forward thrust resulting in up to twice the maximum speed.
      When active the fuel consumption is very high. Care must be taken as
      all flight controls are manual.

      Reverse Retros or 'Sphinx' Manouvre
      
      Pressing 'Q' activates the reverse rertro-boosters.






      SPECIAL MANOUVRES
      

      Needle Manouvre (F7)
      
      The craft rises vertically away from the ground at maximum speed for
      a short while. Automatic flight safety systems are operational while
      in 'Needle' mode. Fuel consumption low.

      Hawk Manouvre (F8)
      
      The craft descends vertically and at a high speed. As soon as it is
      close to the ground it aborts the manouvre. Fuel consumption low.

      Duve Vulture Manouvre (F9)
      
      When in this mode the craft can fly at high speed without any danger of
      crashing on the ground. All the automatic safety systems and all the
      engines become operational simultaneously. Any errors that the pilot
      makes are immediately corrected by the on-board computer.
      Fuel consumption high.

      Jackal Manouvre (F10)
      
      The craft can be placed in any angle (usually pointing down at 45
      degrees: this should be done at a standstill). The 'Jackal' will then
      enable the pilot to move either forward or backwards at the same
      constant height while maintaining the last flight angle instead of
      following the trajectory of the nose. Craft must start the phase at a
      standstill to adopt this manouvre. Pressing F10 again or the 'CTRL' key
      or button 2 on the joystick/mouse will exit this mode. Automatic flight
      safety systems are operational while in 'Jackal' mode.
      Fuel consumption low.

      Isis Manouvre (F11)
      
      The craft rotates round its centre of gravity facing away to the
      horizon without banking. The craft must be at a standstill to adopt
      this manouvre. Fuel consumption low.

      Orion Corona Manouvre (F12)
      
      The craft targets a building at a standstill and the craft begins a
      slow clock-wise navigation of target, maintaining the same altitude
      while the nose of the craft always points to the centre of its
      circular trajectory. Fuel consumption medium.

      Sphinx Manouvre (Q)
      
      The craft cuts acceleration and fires forward retros, instantaneously
      throwing the craft into a fast reverse (maximum speed is possible).
      Automatic flight safety systems are active during this manouvre.
      Fuel consumption high.

      Afterburners (TAB)
      
      Extra thrust forward for a short period of time. Up to 100% faster
      than the usual top speed. Fuel consumption high.


      USING THE HORUS PROGRAM GRABBER  (G)
      
      While the program runs, in demo mode or not, the current visible frame
      on the screen can be saved in the current directory on the hard disk
      by pressing the G key. Up to 100 frames can be saved each time that
      the program is run. The names of the files in low resolution are
      GRABL00.TGA, GRABL01.TGA .... GRABL99.TGA. In high resolution the names
      are GRABH00.TGA, GRABH01.TGA .... GRABH99.TGA. Note, that if you exit
      to DOS you must copy all the grabbed files in another directory for
      safe keeping, otherwise any new grabbed files will overwrite the old
      ones. Each time that the program is run the counter starts at 0 and
      increments towards 99 after each grab.

      The files are saved in uncompressed Targa format with the TGA
      extension. These files can be converted to other formats by using a
      utility such as Autodesk's ANICONV.EXE which is included in the
      ANIMATOR and ANIMATOR PRO packages.
