Many of you may already be # aware of this annoying mind challenge after playing the popular waste of # time from Bethesda Softworks on your favorite pc or console. # # The minigame presents a "green screen" like terminal with what apparently # is a dump of some mainframe's password program file. In amongst the noise # are a set of words that are all the same length. As you hover your mouse # over each of these words, that word becomes a guess that you may take on # the command line. The following ascii excerpt of an example screen is # taken from DrAgRoS' terminal hacking guide from gamespot.com (I was too # lazy to type one on my own) # # --------------------------------------------------------- # ROBCO INDUSTRIES (TM) TERMLINK PROTOCOL | # ENTER PASSWORD NOW | # | # 4 ATTEMPT(S) LEFT : [] [] [] [] | # | # 0xF92C %*-}'!.-[)#! 0xF9F8 :($-?!!}'%_( | # 0xF938 (>!];-/\[=(, 0xFA04 /?;_;#"]!!:, | # 0xF944 @PARTNERSHIP 0xFA10 %'%{.@@}#?|+ | # 0xF950 S=\]%,*?++:] 0xFA1C ="||^<@-|PUR | # 0xF96C #\--(??%=^\? 0xFA28 IFICATION(^S | # 0xF978 ]$/!]'|]=}"| 0xFA34 ECLUSIONIST> | # 0xF984 REPRIMANDING 0xFA40 .,"CONSTRUCT | # 0xF980 :(%CIVILIZAT 0xFA4C ION@'_'=':'> | # 0xF99C ION:(]=%?|{A 0xFA58 =!.;/'+.@'/D | # 0xF908 PPRECIATION' 0xFA64 ISAPPEARING% | # 0xF9A4 :*CONVERSATI 0xFA70 ,]%?<TRANSMI | # 0xF9B0 ON=.:="+$@#< 0xFA7C SSION,}"/'}, | # 0xF9BC ['<'%':}!%;+ 0xFA88 \"%\^?<(|APP | # 0xF9C8 '('#'?,.%*!+ 0xFA94 REHENSIVE}<+ | # 0xF9D4 =\.\?/(!|#?< 0xFAA0 "<\^+].^^'._ | # 0xF9E0 |[)???@?%{CI 0xFAAC ;++}{=/'\ENC | # 0xF9EC RCUMSTANCE_= 0xFAB8 OUNTERING*}; >[] | # --------------------------------------------------------- # # ------ # | | # POWER ------ # # # You only have four guesses (although as the guide mentions, there may be ways # to reset the challenge).
