"Resident Evil Zero" received generally positive reviews. Critics praised the graphics and audio for building a haunting atmosphere. Opinions on the new partner and item systems were mixed. Some found the changes were an improvement and added new layers of strategy; others believed the changes were cumbersome or non-innovative. The controls were panned as outdated and Capcom was criticized for not evolving the series' tank controls. The game was ported to the Wii in 2008, and a high-definition remaster was released in January 2016. These re-releases received mixed reviews due to lack of improvements made to the original. "Resident Evil Zero" was commercially successful, having sold over 4 million copies across all platforms.
