The U4GM Guide of How to complete Quarantine in BO7

[Smsnaker235]

Ready to tackle "Quarantine" in Call of Duty Black Ops 7? This mission mixes stealth, fire fights, and a tense finale. You can test your approach in a CoD BO7 Bot Lobby to warm up and try out weapons without pressure. The Bot Lobby gives a calm space to learn enemy routes, practice aiming, and find the best loadout before you enter the real mission.

Phase 1 — Breach and Clear

Start by moving in slow and steady. Use cover and check corners as you get into the compound. Assign one player to watch the left flank and another to watch the right. Use flash or stun grenades if enemies pile up near choke points. Keep your shots short and accurate. If you rush, you will trigger heavy resistance and lose lives. Clear each room methodically and mark any patrol routes you see for the team.

Phase 2 — Find and Hack the Transmitter

When you reach the interior, look for the transmitter in guarded rooms or behind locked doors. Prepare for a fight when you start the hack. One player should start the hack while the others set up defensive positions around a doorway or stairwell. Place a teammate near an exit in case you need to pull back fast. Watch the hack progress and call out enemy spawns. If the hack gets interrupted, move to a safe spot and try again after clearing the area.

Phase 3 — Dr Falkner Showdown

Dr. Falkner fights differently from normal enemies. He uses heavy attacks and special gear. Keep moving and use cover well. Save a few high damage items for the boss phase, like armor piercing rounds or a strong grenade. One player should focus on watching Falkner’s tells and calling the timing for full team bursts. Another player should carry extra ammo and supply it when the group falls low. If you need to fall back, pick a spot with good sight lines and few approach angles.

Phase 4 — Penthouse Intel

After Falkner, push up to the penthouse slowly. Check each room for hidden documents or data drives. Search desks, safes, and terminals. Assign one player to scan terminals while others cover doors and windows. If you miss an item, backtrack now rather than later. Missing intel can force you to go back under enemy pressure, and that wastes time and lives. Stay alert for reinforcements and clear each floor before you move to the next.

Phase 5 — Plant the Charges and Escape

Find the marked spots near the elevator shaft and plant the charges. Once the charges are down, you must hold a tight defense until detonation. Set up crossfire positions that cover the approaches. Use grenades and area denial tools to stop enemy pushes. One player should watch the flank while another watches the core approach. After the blast, move quickly to the extraction point and keep eyes on the squad so nobody gets left behind.

Practical Tips and Practice Runs

Practice the hard parts in a buy BO7 Bot Lobbies if you can. Use that mode to test breach routes, to time the hack, and to rehearse the boss burst. Keep your loadout balanced so you have ammo, healing, and grenades.
