Are the Covenant in Legendary mode?
Thats the only way to play.
I'll have to let you know after playing Halo2.
Though my initial guess would be the covenant.
The empire ruled by fear like the old roman empire. They relied on the
masses not getting together as one and fighting back.
The covenant just wipe out the population and move on.
o.k they had the Death Stars(tm) but lets face it they were a bit lame.
Then theres the Plasma Sword V Light Sabre...
Does the Covenant have access to the Halo network?
You say that the flood remain neutral but my take on them is they were more of a biological hazard rather then a force. They thought of them just sitting back on their rotting behinds watching the action just don't seem right. More likely they would be as the game and would attack both sides.
