The term is "rail shooter" isn't it? Gih. Whatever. ;)
I love the game, and there are a couple reasons why it would be worth tasing.
The Cyberdyne level would be the reason to watch. You have to destroy X number of objects- so use 2 players and wreck absolutely everything. That's not something that can be done in realtime, I don't think.
Then there are those two chase levels. The damnable red truck always blowing up at the end... it would be nice to see that part being owned with a rusty spoon. I don't think it's even possible to make it through without the truck taking damage, but if it can, that's something.
The helicopter chase wasn't nearly as hard as the first chase, but it would be funny to see how little of the helicopter can actually make it onto the screen before being repelled.
The skynet fight. At inhuman speed. Could be neat.
