Flashback to PSone Metal Gear Solid
Without warning, you're suddenly back playing the original Metal Gear Solid. Even though this sounds like a brilliant little nostalgic nod to the series' past, you ain't seen nothing yet. Seriously, if you loved MGS1, you HAVE to play the new game to see what happens next.
Best bit here, however, has to be the low-poly model from MGS1 used for Snake's face for a split second as he wakes up. Honestly, we wonder about other game devs some times, especially when the likes of Kojima seem to do 'brilliant' with such ease and simplicity.
