Seconds into your first match of Firefight: Gauntlet, you’ll understand the name.

This deviously difficult PvE mode introduces upgradeable attributes, elimination objectives, and auto-scaled difficulty settings to a boss-filled Firefight experience designed to challenge even the toughest Spartans.

Bring your mightiest warriors, because each phase of the Gauntlet is harder than the last.

As endless enemies rush from all sides, your team’s only hope is to eliminate the bosses in each arena to halt their reinforcements and progress to the next encounter.

Combat ranges through five maps connected by a supply area where you can gather ammo and equipment, roll for power weapons, or level up your personal buffs (Speed, Resistance, Regeneration, and Damage) for the onslaught ahead.

Between rounds, you’ll get a chance to upgrade your stats and kit out before the next attack—so make those choices count! Survive five rounds, and victory is yours.

Pro tip: If you can retrieve the Oddball from the Harbinger, bring it back to the supply zone to activate Skull modifiers and boost everyone’s Personal Score during the match.
