Sopwith (computer game)
Encyclopedia : S : SO : SOP : Sopwith (computer game)
Sopwith is a sidescrolling shoot 'em up created by David L. Clark of BMB Compuscience. It runs on the IBM PC under DOS but there is also a port to the Atari 520ST. The game involves piloting a Sopwith biplane, attempting to bomb enemy buildings while avoiding fire from enemy planes and various other obstacles.
Sopwith was created to demonstrate the "Imaginet" proprietary networking system developed by BMB Compuscience. David L. Clark, employed as a programmer at BMB, developed Sopwith as a multiplayer game. The multiplayer function will not operate without the Imaginet hardware and drivers. However, single player functionality was also included, with the player flying alone or against computer-controlled planes. Because of this, the game was widely distributed, even though the Imaginet system itself was not hugely successful.
All versions of Sopwith feature four-color CGA graphics. Sound is provided by the PC speaker in the form of music and sound effects.
The C source code to Sopwith was released in 2000, at first under a non-commercial use license, but later under the GNU GPL at the request of fans.
Gameplay
The player begins at their base (typically a hangar and a runway). From here, they must launch their plane and attack targets. This stage can be a hindrance to inexperienced players, as sufficient speed is needed to get the plane into the air. Insufficient speed will cause the plane to stall and crash.The plane is equipped with a machine gun and a supply of bombs. This weaponry can be used to destroy enemy buildings and shoot down enemy planes. Gauges in the status bar at the bottom of the screen show the remaining lives, fuel, bullets and bombs respectively.
In Sopwith 2, obstacles exist in the form of Oxen and birds. The oxen simply stand on the ground; if the player crashes into one, they lose 200 points and their plane crashes. The birds provide a more challenging obstacle. Flocks of birds move along the top of the screen. If shot at or flown into, the flock will disperse into individual birds. Flying into a bird causes the plane to crash.
If the player manages to destroy all enemy buildings, the plane turns and flies into the sunset. In Sopwith 1, the game ends. In later versions, the game advances to the next level. Successive levels increase in speed; also, in the second level upwards, buildings shoot back at the player's plane.
The Ox was included as an in-joke and refers to an employee at BMB named "Ox".
Versions
Sopwith 1
The original Sopwith game was released in 1984 and is referred to as "Sopwith 1" by fans. This version had a game clock that was tied to the speed of the hardware: because of this, on later PC hardware, it would run faster than originally intended.
Sopwith 2
A new version was released in 1986 and is referred to as "Sopwith 2" by fans. This fixed the game clock problem of the older version. It also added a number of features:
- Oxen and birds as obstacles to the player
- Advancing levels of difficulty; Sopwith 1 would quit after completing the level.
- Improved computer AI
- The ability to play two player multiplayer games over a serial line (though this is apparently problematic).
Sopwith: The Author's edition
Sopwith: The Author's edition (a.k.a. Sopwith: The network edition) was released in 2000 at the same time as the source code. This contained further features over Sopwith 2:
- Improved AI
- Wounded planes
- Heat-seeking missiles and flares
- Heads-up "splats". When hit by enemy fire, bullet marks would appear on the screen, for example.
