EPT - Information
Continued...
Players move around inside Spacestations, Mooncities and the like via 'tube' systems. These tubes have various nodes for locations such as banks, tube stations, etc. The player has to pay a docking tax when they first enter, but in compensation, all tube transport is then free.
Some locations within the tube system will have access limitations. For example, a guard might require a pass, a door might require a key or an entry code, or the player's identity or rank might not be currently sufficient to grant access.
Tube maps help the player to find their way around. A tube map represents nodes with solid discs of different sizes and colours corresponding to what they represent. For example, the Central Bank of Urth is a Bank represented on a map by a large red disc. A standard key is also displayed, explaining the colours of the nodes and the location types.
The player can also move around inside the various spacecraft they might encounter. The larger the ship, the more nodes (or locations) there will be.
The EPT specification as written by Ricardo Pinto is a large and richly detailed series of documents. As previously stated, some documents would have been included in the game packaging, whilst others were just for the programmers and publishers eyes only.
