After Multitude, Smith's game development career continued in Austin, Texas working with Warren Spector at Ion Storm as lead designer on "Deus Ex" as well as its sequel, "Deus Ex: Invisible War". Smith left Ion Storm to work at Midway Games as lead designer on "BlackSite: Area 51". On November 29, 2007, Harvey Smith, as designer of "BlackSite: Area 51", came out publicly to announce how unrealistic the game's development schedule was and through mutual agreement left Midway a day later. He claimed the schedule caused the low reviews due to the fact they were not able to test the game properly.
