Halo 4's Legendary difficulty: the hardest in game history!
 

Why is it so hard? It's because, in addition to having to fight armies of Promethean Knights and Covenant, I also have to contend with a faulty Internet connection which conspires to stop me from unlocking the MkVI armour for use in multiplayer, but also a hard drive that likes to lose all it's progress when I'm 12 enemies away from finishing it.
