He returned to California and started a commercial art studio called Horizon Zero Graphiques with partner Gary Winnick in 1977. He continued working commercially, mostly for video game companies, for the next several years. In 1983, Cirocco, Carl Potts and Alan Zelenetz co-created the series Alien Legion, conceived as "the French Foreign Legion in space." Two ongoing series and several miniseries and one-shots were produced. In 2007, Potts' Alien Legion screenplay was optioned by producer Jerry Bruckheimer and The Walt Disney Company. Bruckheimer exercised the option and bought the script in 2010, hiring Game of Thrones show runner David Benioff to do a rewrite.
