As much as I was down on the game for Act II & III, Act IV is making up for it.
It's not often where the ol' pig gets goosebumps while playing a game but the first half of Act IV had that in spades. Not only that but the game actually reverts to playtime for most of it instead of never-ending custscenes.
Return to Shadow Moses! Holy shitballs! The intro from MGS1 was a great touch, too.
