Some 16-bit versions featured digitized voices. Some ports featured tricky graphical effects (e.g., the Amstrad CPC version included both mode 0 and mode 1 graphics at a time). "After The War" featured two of the classical "FX" brands of Dinamic, the FX double load (consisting on two separate parts to get advantage of computer memory) and FX giant sprites, that made use of very big sprites that can be even ¾ of the total play area height. Note that those "FX" brands are simply commercial names that Dinamic used to name some features of its games.
