  • One in the Chamber – a classic Free-For-All party game, starts players off with weapon and a single bullet. It only takes one shot to down an enemy, but make sure it's on target or you'll run out of ammo. Earn additional bullets by getting kills or with a melee attack. You've got three lives, so make 'em count.
  • All or Nothing – In this Free-For-All mode, players have limited armaments: only a handgun and a Throwing Knife. Aim with precision and get the most kills to claim victory.
• New Weapons:
  • Rytec AMR (Sniper)
  • Kali Sticks
• New Warzone Content:
  • Juggernaut Royale – Battle Royale mode variant, the massive Multiplayer Killstreak drops into Verdansk – three airdropped care packages, specifically, hold the Juggernaut suit. Head to one of the marked locations to capture and don the Juggernaut suit. Once you have it on, you'll have higher health, a mini-gun, and a sweet music track to accompany you during the Warzone match. You'll still be able to ride in vehicles and climb ladders, and your zero-fall damage will be accompanied by a ground pound of damage that impacts anyone in the immediate area. If any of the Juggernauts are sent to the Gulag, after a brief delay period, a new Juggernaut care package will be marked on the Tac-Map and deploy into Verdansk.
  • Realism – Realism in Warzone follows the same rules as the Multiplayer mode. You'll have a minimal HUD and deal increased headshot damage. Make sure you make the most of it, but fire with precision.
  • New Contract – Supply Run
  • Weapon Mastery Challenges
  • And More
