[UPDATE] In a statement, Activision confirmed that this patent was only "exploratory," and such a system has not been used in any games.

"This was an exploratory patent filed in 2015 by an R&D team working independently from our game studios. It has not been implemented in-game," a spokesperson for Activision said.
