Bioshock Infinite - All Blue Ribbons
This is my method on getting all of the blue ribbons. I recommend you to upgrade all of your Vigors and Weapons before doing this.
Also, ignore my fails on [1:16:52 - 1:19:45], I didn't notice it until it was too late.
FYI, This is not done in one run. Only the first level was done flawless. The rest I've compiled each successful blue ribbon wave into a single video so just ignore the blue ribbon counter.
