It seems that after the PC guys hacked into the Modern Warfare 2 and revealed the dev console, new game modes have been found lurking on the disc!
After some crafty hackers got into the developer console within Modern Warfare 2, setting up dedicated servers and generally playing with the settings, someone apparently tried to create some new game modes with success. From within the added console, a number of hidden gametypes like Global Thermonuclear War were also found, in which teams must race to capture - and detonate - a nuclear bomb before the opposing team. Other gametypes discovered were of the escort variety and variations on capture the flag.
This leads to the question, are those things found in the dev console simply edited and discarded content, or, could they possibly be future DLC, just sitting and waiting? We will keep updating as new information surfaces.
