Destruction Zone

Destruction Zone is a science fiction tank war game.
Somewhere in our galaxy lies a quietly floating station, illuminated by the stars, but very dark inside. From time to time a group of challengers travel to the station and turn on the lights, transforming the 'Dark Zone' into the 'Destruction Zone'.
The station is large in area, but the ceiling lies only a few metres above the floor. It is the battle field for the most famous war game in the galaxy. A series of triangular tanks, made up entirely of three huge cylinders, are teleported into the zone and hover in their positions, repelled from the floor and ceiling by strong electric forces. The liquid fuel of each tank can be seen splashing around inside each cylinder and by looking closely inside, many wires and tubes are also visible. Due to the radioactive fuels used, each tank glows softly in a unique colour. As the Destruction Zone becomes even brighter, the tanks start to move. The first round has begun. The tank controllers switch between a range of weapons, blasting their foes in all directions.
As time passes, the tanks glow dimmer, for they are all low on weapon fuel. They wait in corners, absorbing the Zone light until they glow brighter, and then they launch another attack.
When a tank has taken too much damage, it is teleported out of the Zone with the unharmed controller, so everyone lives to play another game. From all around the galaxy, the D-Zone enthusiasts await the next scoreboard update.
Every three rounds, competitors are allowed to spend their hard-earned money in a special D-Zone shop, where advanced weaponry and special tools can be bought for a suitable price.
Sometimes there are not enough willing to play the game which is why robot tanks are often required. Many different robots are available for play, some having special advantages that make them a challenge for even the best known players.
This game is a simulation of the game described above, with each tank being represented by a three point vector image, and controlled using a combination of six different keys: Forwards, backwards, turn left, turn right, change weapon, and fire. The background is generated randomly at the beginning of each round and the Destruction Zone is viewed from above.
Most of the game is easy to work out without any instructions, so the rest of this manual only contains information about what each key does, the scoring system, and a description of each shop item and robot tank.
