To my knowledge, there are at least eight different versions of Sopwith. If you discover more, please contact me and I'll add it to the site.
| Version 
          Name | Description | Author | 
| The original Sopwith, created by Dave Clark of BMB Compuscience, Canada. (Requires the slowdown utility "Moslo" to work on today's computers) | David 
          Clark  | |
| An update of the original Sopwith, created by Dave Clark of BMB Compuscience, Canada | David 
          Clark  | |
| Essentially a modified version of Sopwith 1 with identical gameplay. Only the title screen, with the multiplayer feature option, has been altered. The question of who altered it and why is a mystery. Requires Moslo to play. | ??? | |
| A clone of Sopwith2 with altered text by "Frank and Jeff" with comments about "Barry." | "Frank 
          and Jeff" | |
| A modified version of Sopwith2 by "ah251@torfree.net" that has a changed map, music, and text. It is very difficult to beat a level in Sokwith due to object placement. There is a hidden easter-egg in Sokwith where the outline of the map looks like a... well... you'll have to find out for yourself! | Ah251@torfree.net | |
| A modified version of Sopwith2 by "Samor" that replaces the landscape with rectangular shapes, and alters the music and text. | Samor | |
| A heavily modified version of Sopwith2 by the original programmer, Dave Clark. | David 
          Clark  | |
| An Italian clone of Sopwith2 with altered text ("Aereo" means "Airplane") and no visual multiplayer options. Thanks to Marco for the find! | ??? | |
| Jornand de Buisonjé's new Sopwith version, with Internet Multiplayer capabilities! (Requires Winsock Extensions (sockvxd.exe) to play multiplayer) | Jornand 
        de Buisonjé | |
| Simon Howard's Sopwith port for numerous OSes, hosted through Source Forge | Simon Howard | 
It's now easy to design your own Sopwith mods with two utilities:
| Utility | Description | Author | 
| A simple map editor written in Qbasic (You can read the instructions to run it here.) | Andrew 
          Durdin | |
| A much more advanced level designer in Visual Basic that can import any Sopwith EXE file, make changes using a pen-tool, and export a recompiled Sopwith game with the new map. | Matt 
          Zebrowski | 
And one more honorable mention:
| A side-scrolling Sopwith-esque DOS game with colorful graphics and great gameplay. | Shawn 
          LeBlanc |
