LOL Nicely done :)
I absolutely hate the Flood, and The Library on Legendary is insanely hard and almost no checkpoints come when you need them. Who hasn't shot 343 Guilty Spark at least once. Just one thing... When 343 comes back down, it would have been awsome if you imported one of his remarks from the game like "Stop being human" or "Please stop firing your weapon". Other than that it was great. :)
