As someone who always got lost at the end of 343 Guilty Spark in the original Halo, trust me when I say that this video rocks. Heck, you'll even get the achievement 'Breaking Quarantine' if you follow this tutorial to a T. All you have to do is escape from the Flood quarantine zone in under 21 minutes. Do this, and you'll get a sweet 25G.
Unlock every achievement in every game.
