Click or hold Left Mouse Button to sprint.

Just remember – sprinting reduces your mass. Use it wisely.

Your body’s length is key to survival. The longer you are, the wider are your possibilities on getting other dragons in a trap. But be careful – regardless of mass you achieve, avoid colliding your head with others’ bodies. Single impact means defeat.

Sea Dragon, written by Wayne Westmoreland and Terry Gilman, was one of the most popular games for the TRS-80. It was released in 1982 by Adventure International, which also sold versions for other computers:

  • the Apple II version, written by John Anderson, was released in 1982.
  • the Atari 400/800 version, written by Russ Wetmore (Star Systems Software), was released in 1982.
  • the TRS-80 Color Computer version, written by Jim Hurd (Coniah Software), was released in 1983.
  • the IBM PC version, written by Dan Rollins, was released in 1983.
  • the Commodore 64 version, written by David H. Simmons, was released in 1984.

As far as I know, Sea Dragon was the TRS-80 game that was adapted to the most computers.

According to Wayne Westmoreland, Sea Dragon was inspired by the arcade game Scramble, which was released in 1981. The ending of the game (which involves destroying a nuclear reactor) was inspired by the arcade game Phoenix, released in 1980. Of all the TRS-80 games that he and Terry Gilman wrote, Sea Dragon was his favorite.

Underwater mines

Sea Dragon was described this way in a 1982 Adventure International catalog:

Sea Dragon is a slick, arcade-ish simulation that puts you in commandof a nuclear sub that’s armed to the hilt with deadly missiles andtorpedoes. You guide your submarine past underwater mountains andthrough labyrinthine passages while avoiding webs of explosive minesthat rise from the sea bottom. Additional dangers includemine-dropping ships, enemy attack stations, falling stalactites, anddeadly lasers—any of which could keep you from your ultimate goal:destruction of the incredibly powerful nuclear reactor at the end ofthe undersea course! Maneuver around these dangerous obstacles andsurface to refuel your ever-decreasing air supply—if you can!

The playing field of Sea Dragon scrolls horizontally and is very wide; one advertisement described it as “the equivalent of two dozen screens laid end-to-end.” The goal is to pilot the submarine to the very end and destroy the nuclear reactor found there.

Colliding with an underwater mine destroys the submarine, as does hitting the ground or any of the other obstacles in the water. Another complication results from the need of the submarine to surface periodically and replenish the air supply. This creates a problem when the game moves into a series of underwater passages with no open air.

Sea Dragon was one of the original games featured on the scoreboard in “The Gamer’s Cafe,” and it was often mentioned in the column. Long-time readers of “The Gamer’s Cafe” may remember that Sea Dragon played a pivotal role in the departure of Winthrop from the column.

Like most of the Adventure International games, the various versions of Sea Dragon differ in some details. Several have enhancements specific to that version, such as the voice effects in the Apple II and TRS-80 Color Computer versions. (And who can forget the dancing sailor from the title screen of the Color Computer version!) But the game play and the look of the games remained quite close to the TRS-80 original.
