The launch day for Call of Duty: Modern Warfare 2's almost here, and Infinity Ward has detailed some of the changes implemented from beta feedback. There are some pretty notable updates coming with the game's October 28 release.

First, Infinity Ward revealed that beta feedback was used to increase enemy visibility. The developer said this was implemented by adding diamond icons above the heads of enemies to clearly identify opponents in the match. Additionally, tweaks were made to lighting and contrast for improved enemy visibility.

Modern Warfare 2's audio also received a few adjustments before release. The overall range of footstep audio has been updated to allow enemy players to get closer to targets before they are able to detect footsteps. Players can also expect teammate footstep audio to be quieter.
