Probably the online mode in the re-release of MGS3, MGS3:Substinence, I believe one of the game modes has you chasing down a rubby-ducky then holding onto it the longest or something.
Although I have heard of a true Metal Gear Online being a possibility, with the MGS3 re-release being a testing ground.
