1266 Styx Master of ShadowsThat ' s a hard choice , but I would probably have to go with Halo Reach ' s story . The first time I played it , I played it coop with a friend , and my god if we weren ' t both ready eyed by the end . The way the writers make you connect to each member of Noble Team , makes it all the more sad watching them die off one by one , from the sudden death of Kat , do the badass one of Emile . The last mission as well , Lone Wolf , just the constant waves of enemies and you fighting as hard as you can . Definitely one of my favourite stories . Thanks for the giveaway ! <| sep |> I imagine that most of the lifeforms on the Kett ' s home planet evolved with similar bone armour , and so it ' s just a beast of war .
