10k quick halos. Destroy everything in the train station in chapter 1. The train will start to move. Jump on and ride through the tunnel, you'll get 10K halos. Not as much fun as spamming the boss in chapter VII but good for beginners who are just starting the game.
The patch fixed a few things..I think. Yeah the loading times are cut down but it seems like the game plays faster and some of the screen tearing has been reduced.
