# Duke2Reconstructed: matching Duke Nukem II source reconstruction

> Duke2Reconstructed rebuilds Duke Nukem II's DOS source in C and assembly from disassembly of the original executable. The author reports that an era-appropriate build produces a byte-identical binary after LZEXE compression, while original names and file organization remain approximations.
