An early prototype of High Seas Havoc for the Sega Genesis.



  • The game's internal header refers to 1992, but it is not certain that this is the year this build was made.
  • The cartridge label calls the game by its name in Japan, Captain Lang. The in-game title, however, refers to it by its US release title. The artwork used is an earlier iteration of the game's logo with more details that were later scrapped for the final logo.
  • Many palettes for characters, including the player's, are different and generally are more brighter.
  • Captain Lang has a different facial expression on the title screen.
  • Stages don't have an introductory screen and head straight to the start.
  • Holding jump will allow the player to float in air.
  • Most levels are empty and void of any objects, with incomplete assets showing up every so often.
  • Most levels also are mute. Only a few tracks are available in the game's sound test.
  • Any level bosses are static and do not move or hurt the player.
