Duke Nukem II: 2 Open Source Clones Compared

Duke 2 Reconstructed is a reconstruction of the original source code meant for documentation, preservation, and DOS source mods — its own readme states it compiles to a binary identical to the original and points players who just want to play the game on modern systems to Rigel Engine instead. Rigel Engine is that modern reimplementation: a drop-in replacement that runs natively on current systems, adds modding support beyond the original game, and requires the original game's data files to run.
