This page describes advanced PHALANX base facilities, and how the game should handle them.
Advanced base facilities versus regular base facilities
Advanced base facilities are upgrades to regular base facilities. They perform better in every way and are required for some high-performance tasks that their old counterparts can't handle. However, they typically also take up more space in the base, so upgrading old facilities may include reorganizing the base. Generally speaking, old facilities can not perform the same tasks as their upgrades, so the player will have to build the new facilities in order to complete the game.
List of advanced base facilities
Advanced Radar Facility
This is an upgrade to the regular radar facility. It has increased range and does a better job at detecting UFOs, especially higher-end UFOs. Note that radar towers can not be upgraded.
Advanced Research Facility
This is a 2x2 facility. It can employ more scientists than a normal research facility, for example 30. The output of a fully staffed Advanced Research Facility should be higher than that of four regular research facilities. The Advanced Research Facility is required to research some high-end techs. Scientists in old research facilities can not contribute to such research.
Advanced Workshop Facility
This is a 2x2 facility. It can employ more workers than a normal workshop facility, for example 30. The output of a fully staffed Advanced Workshop Facility should be higher than that of two regular workshop facilities. The Advanced Workshop Facility is required to produce some high-end items, notably high-end interceptors and dropships. Workers in old workshop facilities can not contribute to such production projects.
