Tom Clancy's Splinter Cell: Conviction is the fifth console game in the Splinter Cell franchise. It was released on April 13, 2010 in North America. In this next installment, Sam Fisher has left Third Echelon since the events of Double Agent and begins the story working by himself on his personal mission
Due to the missing night vision feature in Conviction, I was designated for performing a workaround. This addon gives you the possibility of enabling night vision no matter if sonar scan is acitvated, its additional. I don't know why Ubisoft didn't implemented this?! You can choose between different nightvision grades/colors. Right now there are 6 different color grades/nuances included. Google the name of the mod to get images of each mode.
The game never gets so dark that you need night vision.
