I was going for the 500,000 point combo achievement, I got it in single player, but didnt' get anything. I asked one of my friends who has the game about it, and he said it has to be in a mode where you can't use slow motion. So then I went to 2 player mode and got one worth 600,000 and something in trick attack, still no achievement. So does it have to be online or something?
