Worst campaign. The covenant doesn't even look the same anymore they just look like cheap action figures that were thrown in the game just to satisfy real halo lovers. I personally believe if the developers were not obliged to put the covenant in they would have trashed them completely and just had you fight the promethians. The guns are also terrible too, they shoot like plastic toy guns and are too similar to call of duty. I hate this game and strongly recommend that you do not waste your time renting or buying it (unless you just cant get enough of call of duty). May this game rest in a fire underworld.
