ammunition. Development The game's working title was "Blake Stone: Firestorm". The developers were limited by memory constraints and programming issues when trying to add additional digitized voices into the game, and ended up playing pre-existing voices from Aliens of Gold backwards. Just like Aliens of Gold and Wolfenstein 3D, the maps were designed using Tile Editor (TEd). The woman character in the cover art was placed deliberately to catch the attention of viewers in game stores, despite not appearing in-game.
