Banazai's Add-On (also known as Caleb's Revenge and previously Game Leader's Unofficial Add-On) is a single episode fan add-on for Blood featuring seven levels, last updated on November 9, 1998 by Team BANZAI. Partly to facilitate its final release and to lower the download size in the days of largely dial-up connections, it features only new levels and does not contain any new textures, weapons or monsters.
