Modern Warfare 3 is a first-person shooter sequel created by Infinity Ward and Sledgehammer Games. It depicts a war between the US and Russia where players control different characters. The game is popular due to the success of its predecessors, which brought new innovations to gaming. However, some were disappointed that MW3 did not significantly advance the series and had issues like an inability to turn off music or clan tags. It competed directly with Battlefield 3 as similar military shooters. MW3 introduced new playable characters, game modes, and a custom game mode creator.
