# Tower of Babel (1989 video game)

Tower of Babel is a computer game for the Amiga, Atari ST and Acorn Archimedes systems programmed by Pete Cooke, developed by Rainbird Software and released by Microprose Software in 1989. It is a puzzle video game played on a three-dimensional tower-like grid viewed in vector graphics with filled polygons.

## Background

The plot of the game is based on the biblical story of the Tower of Babel. At the height of the tower's construction, while it failed in its original purpose to directly contact God, it caught the attention of a passing Zandorian alien spaceship. The Zantorians descended and left three spider-like robots to help the Shinarians in constructing the tower. However, distrust broke out among the two species, and the humans betrayed the robots, stealing their energy packs (called "Klondikes"). Playing the robots, it is the player's job to find the energy packs to be able to get back home to Zantor.

## Gameplay

The game play is purely puzzle-based. The famous Tower of Babel itself does not actually appear; instead there are several differently-configured 8*8*4 towers (four floors of 8*8 squares each).
The Zantorians robots are called the Grabber, the Pusher and the Zapper. Each of these has different abilities. The Grabber can collect Klondikes and operate various devices, the Pusher can push things further away, and the Zapper can destroy things. In a tower, players can be assigned any combination of these robots, depending on the tower's design. In each tower, the player's goal is either to destroy a set number of objects, collect a set number of Klondikes, or both. Towers with Klondikes to collect need the Grabber, but the other robots can sometimes be superfluous, and indeed, the destruction of these robots is sometimes necessary for the completion of a tower.
Everything in the game is viewed in a realistic 3D vector graphics view, but the actual movement in the game is far more contained than in games usually associated with such graphics, only allowing square-by-square movement in rectangular directions and vertical movement using special lifts.
Various devices, sentry mechanisms and autonomous robots also inhabit each tower. Some of these can be used to gain an advantage, while some hinder progress.

### Editor

Tower of Babel also includes a construction kit where players can design their own towers and save them to disk for later play and distribution. The towers can be password-protected to avoid spoiling them by looking directly at the design.
One feature of the game is the ability to program the robots. Each robot can be given up to eight orders (for example: Forward, Forward, Left, Fire, Right, Forward). In some levels, programming the robots is mandatory, as they need to coordinate their actions in order to solve the level.

### Game objects
#### Block

    Can be pushed around but cannot be shot.

#### Converter

    Changes laser beams into pushing beams and vice versa.

#### Exchanger

    When activated by the Grabber, switches places with it and vanishes. Deflects laser beams back to their source.

#### Flag

    Does nothing but fly in the wind and get in the way. Its only use is to be destroyed.

#### Force up/down

    When activated by the Grabber, moves all lifts not currently holding something either up or down.

#### Freezer

    When activated by the Grabber, temporarily freezes everything in the tower except the robots and the lifts. Once used, takes several seconds to recharge.

#### Glass block

    Can be pushed around. Shooting at it deflects the laser beam back to its source, destroying whoever shot at it.

#### Hopper

    Hops around in a random fashion. Can be destroyed by shooting it.

#### Klondike

    The robots' energy pack. Can be collected by the Grabber.

#### Lizard

    Constantly moves in a straight line. When changing direction, eats away a floor tile. Cannot be shot.

#### Mine

    When it is pushed next to an object, or an object is pushed next to it, it explodes, destroying everything it touches.

#### Prism

    Deflects laser beams at a 90° angle. Can be pushed.

#### Pushing cannon

    Constantly fires a pushing beam. Comes in two varieties, fixed and rotating. Cannot be shot.

#### Time bomb

    When the timer reaches zero, it explodes, destroying everything it touches. Can be pushed.

#### Watcher

    Moves around in a random fashion. Cannot be shot.

#### Wiper

    When activated by the Grabber, eats away all floor tiles in a cross-shaped pattern with itself at the centre.

#### Worm

    Constantly moves in a straight line. Shooting at it makes it reverse direction. When trapped, can be pushed sideways. Moving worms cannot be pushed.

#### Zapping cannon

    Constantly fires a lethal laser beam. Comes in two varieties, fixed and rotating. Can be destroyed by shooting it.
