The prolific art director Viktor Antonov, most notably known for his work and influence on Half-Life 2 and Dishonored, has passed away. The Bulgarian-born artist worked in the film and video games industry during his career and even wrote and designed the graphic novel The Colony: A Structure Celebrating the Triumphs of Technology, featuring the epic story of Gabriel Duban who strives to uncover the truth of a lost city, set in an empire before space-travel dulled the enchantment of Earth-based adventures.
