Netrek: Robots
 The Netrek community toyed with various enhancements before most
servers began validating clients to ensure a level playing field:
  -   INFORMATIONAL-BORG  
       The simplest modification produces a client that merely shows
       the user things they aren't supposed to be able to see: like
       cloaked ships.  They also concentrate information that the user
       usually has to actively request.  The human still completely
       controls the ship.
  
-   COMBAT-BORG 
       These clients add the ability to automatically target torpedoes
       and phasers.  They also often include the ability to more
       effectively dodge torpedoes or manage shields.  The human still
       directly controls all aspects navigation as well as non-combat
       functions.
  
-   ROBOTS 
       Finally we reach the fully autonomous robot.  This is a program
       that knows about the standard netrek programs and has some
       rudimentary ability to make decisions about which program to
       run.  Bots include a command interface that allows a human to
       override this decision process by typing imperative commands.
