To tell the truth, not really. While the game does have a time attack mode and extra weapons and stuff you can unlock by playing said time attack, and extra difficulties, there isn't much hidden stuff.
You'll love this game every moment you play it though. You'll get into it, and feel shit. I teared up small tears of anger at the end, and tears of joyful anger during the credits.
So, not much stuff to do once you beat it other than time attack and trying to get faster times, but it's a damn good game. And I think it's only around 25$ now.
