The map sources are supplied in .jmf (J.A.C.K.) and .map formats, as well as the additional texture .wad file that was not included in the main TWHL Tower 2 release. Two mappers did not give permission for their map sources to be released publicly, but here are the rest of the floors. You may use these sources as you wish in accordance with the license.
TWHL Tower 2 uses Spirit of Half-Life 1.8 as the code base. The .fgd file is provided in this download, and the other Spirit files needed can be grabbed from the TWHL Tower 2 mod itself or from a download of Spirit 1.8.
