This build carries no game data. Pick your Afterlife CD: the CD image (a .bin or .iso file), the .zip it came in, or the CD's files: the .000 bundles (at least ALIFE.000), ALIFE.INI, ALIFE.EXE and the scenarios ASCEN*.ASC. They stay in this browser's storage, so this is needed once.
Don't have the CD? It is on the Internet Archive: archive.org/details/AfterlifeUSA. Download Afterlife (USA).zip and choose it above (or unzip it and choose the .bin).
Afterlife has ended.
