Section 1 – Game Overview

1.1 High Concept

In a twist on traditional street racing games, players take the role of a courier, participating in illegal underground races. Competing with other couriers, using modified bicycles, players’ race through many locations throughout Dundee before completing various puzzles. The game is also designed to encourage people to keep fit while playing computer games and be mentally challenging. Players will utilise their quick thinking ability whilst under pressure and their fitness levels will be challenged during the other parts of the race.
The game is designed for the PC and all home console systems, which already have a large consumer base. The peripheral devices offered by these systems offer a perfect control system for the game.

1.2 Unique Features

Alley Katz benefits from being the first cycling title that encourages users to set up a bicycle in front of their computer screen. This is left up to the user; a simple method is to raise the rear of the bike making it easy to pedal indoors. A heart monitor is connected to the user, and depending on the game situation, the player must either reduce or increase his heartbeat.
The use of standard cycles as the vehicles of choice in the game is unusual. The variety of designs that the standard bike has had over the years allows for a large choice of unique vehicle for the players to choose from. Examples include tandem, recumbent, choppers and unicycles.
Combining the racing and puzzle genres is uncommon providing a unique experience for the player.
