Take this with a grain of salt, but this clip sure looks like it's revealing some new multiplayer modes for Modern Warfare 2, found lurking somewhere in the game's code.
There are three modes in total: VIP (just like Counter-Strike), Capture The Flag (with a single flag between two teams) and Global Thermonuclear War, which one side has to capture. Once captured, the thing goes off, killing everybody.
If you squint through all the garbage written on-screen, you can make out allegations that these modes are all tucked away on the disc waiting to be unlocked as DLC. Makes sense on a basic level, but the bonkers language isn't helping their cause.
