No link but...
The final level of COD MW2, where you're still controlling it but it feels like a movie. Where Price is fighting the General.
Trying not to let lose any spoilers if people haven't played it! ha.
Maybe it's just me,
as I haven't actually played MGS4,
and I'm a big fan of the first one,
but that fight scene looks like a crap and very similar version of the Snake vs Liquid on top of Metal Gear Rex at the end of MGS1.
