The early access to Call of Duty: Modern Warfare 3's campaign has divided fans. Despite topping Steam's best-selling charts, players are reportedly requesting refunds because of the single-player mode's length.

First impressions of the single-player campaign have been middling at best. Chief amongst the complaints is the story mode lasting an average of only four hours, its lackluster level design, and reused assets from previous games. Others have been critical of the open combat missions lacking structure or challenge.

Call of Duty: Modern Warfare 3 has topped sales charts in its early access period, despite facing criticism from some of its players and, most especially, critics. The latest Call of Duty game has been the number one seller on both Steam and the PlayStation Store. While many doubted that Modern Warfare 3 could attract fans due to its mediocre single-player campaign, anticipation for the game's multiplayer and zombies modes have clearly driven strong sales numbers.

However, not everyone is happy about Modern Warfare 3. Most of the outrage has spilled all over the internet, but a lot of it is especially concentrated on Reddit. There, players are sharing the refunds they've initiated on Steam after playing through the short campaign. The refund requests have been a hot topic on the forum site with players being divided about the importance of the single-player game mode.
