Up to eight players will work together to complete five rounds of "increasingly difficult, dynamic objectives set against a timer." These changing objectives should make every single game a bit different, too, so you won't just be going through the motions of slaughtering wave after wave of AI enemies. Firefight scenarios will also have the "most on-screen enemies in the history of the franchise," from swarms of those pesky Covenant grunts right up to new, "Mythic" bosses (gulp!). And because it's a Warzone game type, you can use your REQ Cards to summon vehicles, weapons and power-ups if/when things get a little hairy. One of the only details we're still lacking at this point is when we'll be let loose on the Covenant scum, though the new mode is down for release sometime "this summer."
