Optimal Scorestreak Loadout  
1. UAV: Provides essential map awareness.  
2. HARP: Highlights enemy locations for strategic planning.  
3. Chopper Gunner: Racks up kills quickly, especially in open maps.

If you want to unlock the guns in BO6 quickly, then you can buy bo6 bot lobby from U4GM, which will help you to proceed more smoothly in the game. 

 The Hardcore Scorestreak Cycle Strategy  
1. Earn All Streaks: Play conservatively until you unlock UAV, HARP, and Chopper Gunner.  
2. Deploy Chopper Gunner: Use this streak to clear out enemies efficiently.  
3. Reset Streaks: Intentionally die after deploying all streaks to start the cycle again.  
4. Rinse and Repeat: Use the UAV and HARP combo to quickly regain points for another Chopper Gunner.

 Best Maps for Scorestreak Cycling  
- Nuketown: Tight spaces ensure fast streak accumulation.  
- Cartel: Provides open areas for Chopper Gunner kills.  

 Key Tips  
- Play aggressively but smart—maximize kill chains for bonus points.  
- Use suppressors to stay off the radar.  
- Coordinate with teammates to control objectives and extend matches.

With this strategy, you can achieve sky-high kill counts and maintain map control throughout hardcore matches.
