the story is not a central focus of the gameplay. The main resource in the game, used by both races, is trash. Trash is used as a building material for almost every unit in the game. It must be collected by Dump Trucks or Thralls, which are the collection and building units for humans and mutants respectively. Both of these units are collectively referred to as peons. There are two other resources in the game, Gas and People. Gas is used as a resource only by humans, while people are as a resource only used by mutants. Gas is gathered by building a refinery on top of a gas site. The refineries in trash, unlike such buildings in other games such as StarCraft, do not require continuous collection. People are acquired from unarmed huts, and must be collected by thralls. In addition to that, there are special building sites in the game. Most core buildings can be built without the need of a special site. Such buildings mainly include unit-producing buildings and resource buildings. There are three types of sites in Trash, they are: toxic waste sites, precious metal sites, and gas sites. Every race has upgrades for units or special structures which can only be built on such sites. Destroying a structure built on such a site does not destroy the site however the site can be destroyed by a military unit, unless it is a gas site. Gas sites, however, must be discovered through special detection and are generally rather more scarce than the other sites. Structures in trash must be connected together by pipe. Pipe is an inexpensive structure that is built together, and forms the basis of logistics in Trash. Unlike other RTS games where resources seem to magically pop from one place to another where needed, in Trash they must travel through pipe. This also applies to technologies which are researched. Technology can be shared with an allied player by constructing a pipe to link your pipe system with your ally's. If the pipe between two bases of the same player is broken, the two bases become effectively isolated, as a result, the resource indicator is divided into two in order to show readings for each base. Then the player can only use the resources available on one pipe network for building on that network, unless the pipe is rebuilt. Multiplayer games Multiplayer games are
