the game appeared in 1993 on the amiga and pc dos computers and was subsequently ported across to a wide variety of other formats. the dos version used the standard 320x200 256-color resolution (mode 13h) just for the planning and main menus, with the tactical simulation part rendered at 640x480 with only 16 colors. the higher resolution permitted finer detail in the graphics and allowed for the illusion that more than 16 colors were used by means of dithering. similar graphics and same levels design were used in the macintosh, 3do, atari jaguar and riscpc ports.
