The script to Resident Evil Survivor was written by FLAGSHIP writer Noboru Sugimura, who had also previously written the script to Resident Evil 2. Early in development, the game was intended to be titled "BIOHAZARD GUN SURVIVOR: Behind The Mask" as a working title as seen in an early trailer of the game and evident by a leftover texture in the game files, eventually the name was changed to "Biohazard Gun Survivor / Resident Evil Survivor" without the extra subtitle.
