Todd Jason Replogle (born 1969) is an American video game programmer best known as the co-creator of the Duke Nukem series. He wrote six 2D action games for MS-DOS released as shareware by Apogee Software between 1990 and 1993. This included Duke Nukem and Duke Nukem II, which were side-scrolling platform games.
After Duke Nukem 3D, Replogle started some technical experimentation into what would later become Duke Nukem Forever. He retired from the gaming industry in 1997. The last game Replogle was known to be working on was called "Mr. Fist". This was something he showed to 3D Realms, but it was never published.
