Well, the sword isn't all that good anyway. It's more of a noob weapon, but don't get me wrong, you can definitely do some damage with it. Give me a Battle Rifle over the Sword all day, but not on Midship..
Never got into MP on Halo, and I was reluctant to try it on Halo 2, but I am certainly glad I did, it just kicks ass. Maybe I'll try out Halo on Live soon, just for shits.
