If you’re grinding to unlock the Grim Reaper Scorestreak in bo6 bot lobby, chances are you already know about the 622,000 XP requirement across Multiplayer and Zombies. While many players focus only on PvP, Zombies mode can offer huge XP gains—if you know what you’re doing.

This blog is your complete guide to using Zombies to farm XP efficiently and hit that unlock milestone faster.

🧠 Why Use Zombies for Grim Reaper XP?

Unlike Multiplayer, Zombies doesn’t require as much sweat to earn XP. You’re in a controlled environment, enemies scale up over time, and you’re free to experiment with loadouts and weapons for max gain.

Top Reasons to Use Zombies for XP:

• Lower stress than PvP

• More XP per match over time (long rounds = big gains)

• XP from kills, perks, revives, and contracts

• You can stack weapon XP and progression

🎯 XP Targets: What You’re Aiming For

To unlock the Grim Reaper through Zombies alone, you'll need approximately:

• 310 matches averaging 2,000 XP each

• 60 long runs averaging 10,000–12,000 XP each

• 20 elite matches at 25,000+ XP per session

Ideal strategy: Combine XP farming in Zombies with Multiplayer objectives to balance the grind and avoid burnout.

🔫 Best Loadouts for XP Farming in Zombies

The goal is kill efficiency and survival. The longer you stay alive, the more XP you earn.

🧪 Loadout #1: Critical Kill Grinder

• Primary: M16 w/ Headshot Multiplier attachments

• Secondary: Any pistol with fast reload

• Field Upgrade: Ring of Fire (boosts damage in stationary zones)

Strategy: Camp high-traffic zones. Focus on critical kills (headshots) for bonus XP.

🔥 Loadout #2: Crowd Clearer

• Primary: Shotgun with Dragon’s Breath

• Secondary: Launcher (AOE support)

• Field Upgrade: Frost Blast or Energy Mine

Strategy: Control chokepoints and farm waves with area damage. Shotguns with spread can down groups fast.

⚙️ Loadout #3: Objective Runner

• Primary: SMG with high mobility (e.g. KSP or MP7)

• Perks: Stamin-Up, Jugger-Nog, and Deadshot

• Field Upgrade: Aether Shroud

Strategy: Focus on completing in-match contracts for bonus XP and currency.

🧾 Zombies Contracts = Hidden XP Boosts

Contracts are side-objectives you can accept mid-match (available near terminals or base zones). Completing these gives:

• XP

• Essence

• Weapon unlock progress

• Special rewards (e.g. Pack-a-Punch mods)

Always grab 1–2 contracts early. They scale up with your match time.

🎮 Game Mode: Which Zombies Playlist to Choose?

Pro Tip: Run 2–3 Endless matches per session with high kill efficiency, and you’ll stack XP faster than average.

📈 XP Farming Tips for Zombies Mode

1. Go for Critical Kills
   – Headshots yield more XP than body shots.

2. Stay Alive Through High Rounds
   – XP bonuses are awarded after each wave and scale with difficulty.

3. Stack Weapon XP Tokens
   – Activating double XP tokens affects both Zombies XP and weapon progress.

4. Use Scorestreaks in Zombies
   – Killing 10+ zombies with a single Reaper rocket? That’s bonus XP right there.

5. Play with a squad
   – Team play enables more control, revives, and shared XP bonuses.

🛑 Common Mistakes to Avoid

• Leaving matches early – You lose all wave bonuses if you exit mid-game.

• Skipping contracts – That’s 2–3K XP left on the table every session.

• Neglecting your loadout – Weak weapons = fewer kills = less XP.

• Ignoring revives/support – Healing teammates gives XP too.

📊 How to Track Progress

Black Ops 6 tracks XP earned toward Rivals and Scorestreak unlocks on the main event screen. You can also check:

• Match summaries (XP earned per kill/class)

• Lifetime stats for Zombies mode

• Weapon progress (if dual-grinding for unlocks)

🎯 Final Thoughts: Grim Reaper via the Undead

Zombies isn’t just fun—it’s an efficient path toward unlocking one of the most destructive Scorestreaks in the game. With the right:

• Loadout

• Strategy

• Team

• Focus on XP efficiency

…you can use Zombies mode to knock out half (or more) of the 622,000 XP requirement and still enjoy the bo6 bot lobbies grind.
