Call of Duty: Modern Warfare 3 has turned out to be a major disappointment, with its underwhelming and shockingly short campaign in particular having drawn widespread criticism.
Apparently, some amount of work was put into the project, though before it could get too far in development, it had to be shelved, with Activision informing Sledgehammer that it would instead be working on Call of Duty: Modern Warfare 3.
In 2017, it was reported that before development began on Call of Duty: WW2, the studio’s first choice was to work on an Advanced Warfare sequel.
In addition to that, another interest tidbit that the report has revealed is that Modern Warfare 3 was apparently not even the game Sledgehammer itself wanted to work on.
