[3] Simeon Pashley regarding Shadow Warriors : "I joined Teque Software as a Amiga / ST programmer and I continued to work on those platforms, gradually working on larger and larger projects with the biggest one being, Amiga+St+C64+Spectrum+Amstrad by 6 people for 17 weeks! Wow! Yes, that’s how long it took us to make a game back then. We were always trying to push what the St/Amiga could deliver and my best commercial game on those platforms included streaming from floppy disk, borderless full-screen scroller with loads of sprites. That game was Shadow Warriors."
Based on 1988 Tecmo coin-op. Alternate name: Ninja Gaiden
Instructions (English) [Budget, Hit Squad] [Source: Atari Mania]
Hold down ‘5’, ‘J’, ‘V’, ‘ESC’, ‘F2’, ‘RIGHT ALT’, ‘HELP’, ‘CTRL’, , ‘(‘ (numeric keypad) and ‘ENTER’ (numeric keypad) while the title screen is displayed. The bottom of the title screen will become purple. During play use any of the following keys:
‘1’______________For more energy (player 1)
‘2’______________For more energy (player 2)
‘HELP’_________________________Skips levels
‘Q’___________________________Invincibility
ANOTHER CHEAT:
When you reach the continue option screen and, if after the word credit, it says 1, start tapping the ‘1’ and ‘2’ keys alternately, all the way through the change disk prompt until both men fall from the sky. This gives you infinite lives.
