Map prefixes and suffixes

Common traditional naming conventions for maps for some Half-Life and Source games use a small prefix (often two or three letters) followed by an underscore at the beginning of the map name. Ex. "de_dust", where "de_" is the prefix and "dust" is the map name.

Official prefixes are as follows:
