Tips
  • For Claymore Shot, place Claymores in high-traffic areas where enemies are likely to walk into them.
  • For Assault, SMG, and LMG Expert challenges, stunning your target can help line up headshots, but take your time to ensure accuracy.
  • For Last Stand Veteran, use a reliable pistol like the USP .45 and consider Hardcore modes for increased damage. Stopping Power perk is also beneficial.
  • For Master Chef, simply throw cooked grenades at enemies.
  • For Airstrike Veteran, coordinate with a UAV (Unmanned Aerial Vehicle, which reveals enemy locations on the minimap (the small circular map in the bottom-left corner of your screen)) and aim slightly ahead of moving targets.
  • For Chopper Veteran, use your Chopper killstreak reward as soon as you receive it.
  • For Stun Veteran, use stun grenades in areas with enemies, which also aids in completing Expert challenges.
  • For Multi-RPG and Clay More, aim for groups of enemies or plant Claymores in high-traffic areas or small hallways. Patience and luck are key.
  • For Stealth, attach a silencer to a weapon you are proficient with.
  • For Invisible, try sniping on maps like Pipeline, Overgrown, and Crossfire where prone positions offer good vantage points.
  • For Counter-Claymore and Counter-C4, place the explosive in a single-entrance area, hide, and shoot the explosive when an enemy approaches. The Sonic Boom perk can be helpful.
