Call of Duty: Modern Warfare 3 will feature support for one of the most common -- and commonly overlooked -- disabilities. Responding to a fan question, Sledgehammer Games confirmed that it is working on a Color Blind Assist option for the title, similar to the option found in Black Ops.
Color blindness impacts roughly 6% of the general population, and men are especially susceptible to it at a whopping 9-12%. Since men at least seem to make up the vast majority of COD players, some are bound to be color blind. The problem can manifest itself in color-coded objective markers or enemy identification, so a shift in tone helps make the game interface clearer.
We've seen more of a push to include disability features in games, from subtitles for hearing impairments to color blind options, and even occasional controller mapping to account for mobility impairments. Most fixes are relatively simple, and open up the game to a wider audience, so developers are getting on-board.
