The single player is still awful and not much changed really.
Half-Life 2 is one of the very, very, VERY few games I'd ever give a 10/10. Honestly the game needs no explanation as to why it's a 10/10, if you've played it you know, if you haven't then go play it.
8/10 still playing it. Would give a 9 or 10 if it wasn't for the long ass restarts if you ever fail any part of a mission.
