How Duke Nukem II’s parallax scrolling worked
Ha! You call that parallax scrolling? Then take a look at this (Amiga, 1993): https://www.youtube.com/watch?v=BoiHk_3siYg. In the first level, the bands of clouds are moving in (I think) 6 different levels of parallax, and also the mountain range and swamp below has different levels of parallax. Ok, this was a game that, as one reviewer put it, "squeezes all the graphic power out of the Amiga". Would you believe that this was a computer which was only capable of displaying 32 colors at once? Ok, that was without tricks of course, and this game probably uses every trick in the book...
