Heh, this is actually kinda funny.
In the PC version of the game, it seems Infinity Ward forgot to delete some of the comments some of the staff members left in the release patch notes on Battle.net. In it, the studio mentions how the addition of the Gun Game mode should net the studio some “positive sentiment” from the community. Not only that, but even how footsteps audio is handled, is touched upon too, with one dev commenting that this is a “hot topic” among the community, and how the changes made aren’t the ones the community wants to see.
