Lone Wolf

This is a post-credits last stand against the Covenant. You'll be vastly out numbered by the enemy, making it near impossible to survive forever.

You have a great height advantage and a mounted turret from your starting position, making it a great place to perch and take out enemies. You can use this as an opportunity to gain bonus points until you are overwhelmed. As your visor starts to shatter, you'll know the end is near and the conclusion of Halo Reach.
