One of the most celebrated aspects of the v20181009 update was the sheer volume of environmental content. The patch introduced to the game. Instead of building entirely new assets from scratch, Firaxis took a "best hits" approach. They remastered classic maps and scenes from XCOM: Enemy Unknown and XCOM: Enemy Within . Stepping onto a modernized version of the original "Police Station" or the dam from the first game provided a powerful sense of nostalgia for veteran players.
