This guide will walk you through the steps, challenges, and tips to efficiently complete the grind and showcase your mastery of this special weapon. If you want to unlock the weapons in the game quickly then bo6 bot lobby service available in U4GM will be the best option for you which will save you a lot of time.

Step 1: Headshots
The first challenge requires landing 100 headshots. To speed up this process:
1. Use Hardcore Mode: Enemies go down faster, making headshots easier.
2. Equip Accuracy-Boosting Attachments: Use optics like the red dot sight for better precision.
3. Map Control: Focus on tight maps with predictable engagements.

Once completed, you'll be ready for movement-based challenges.

Step 2: Movement Kills
- Kills While Moving: Get 50 kills while actively moving.
- Kills While Sprinting: Achieve 30 kills while sprinting.
- Use perks like Lightweight or Double Time for faster mobility.
- Combine this with smaller maps for consistent engagement opportunities.

Step 3: Kill Challenges
Now comes the grind for consistency:
1. Double Kills: Achieve consecutive kills quickly without dying.
2. Triple Kills: Rack up three rapid kills in a row.
3. Five Killstreaks: Secure five kills without dying, ten times.

Pro Tip: Hardcore playlists or close-quarters maps like Rebirth Island offer the ideal environment for these challenges. Equip a suppressor to stay off the radar while chaining kills.
