After watching the first few seconds, I thought it to be a complete re-make of ForrestFire101's Film, but the joke turned out different. Though I don't play halo, or follow it, I know an energy sword (if that's what it's called) is powerful, and this made the ending predictable. Though the use of swears doesn't benefit to the video, it does add slight realism to what is said now when people talk when playing games.  The run cycle could use some work, and since the rest of the animation was basically easing in and out with the guns and when they talked, that's all I can say on the animation. Also, it would have been nicer to see some effects from the energy sword, because when i think that, I see energy: sparks, glowing, and vibrating. Overall it was okay.
