damn you and your questions, pitting the two greatest Sci-Fi franchises against each other.
Given the developments and outrageous effects in Forward Unto Dawn, actually seeing an ODST descend from the edge of the world in a coffin, hammer into the ground, and fly out of this capsule guns blazing is just plain bad-ass. An ODST would be hard to beat, even for an ARC or a Commando, but an ODST against a Stormtrooper.
Mike Tyson could punch Zach Galafinakis again, and i think that would be as fair a fight and ODST v. Stormtrooper
The very existence of flamethrowers proves that some time, somewhere, someone said to themselves, "You know, I want to set those people over there on fire, but I'm just not close enough to get the job done." -George Carlin
