I can provide you with some general tips to improve your gameplay and increase your score:

Master the controls: Familiarize yourself with the game's controls and practice using them until you feel comfortable. This includes movement, aiming, shooting, and switching weapons. Adjust the sensitivity settings to suit your preference.

Understand the game modes: Call of Duty offers different game modes, such as Team Deathmatch, Domination, Search and Destroy, etc. Learn the objectives and rules of each mode to play strategically and contribute effectively to your team's success.

Map awareness: Pay attention to the layout of the maps and memorize key areas, chokepoints, and high-traffic zones. Knowing the terrain will help you anticipate enemy movements, find good vantage points, and plan your strategies accordingly.

Aim and accuracy: Work on your aiming skills by practicing your hand-eye coordination. Try to aim for the head or upper body for maximum damage. Additionally, burst firing or controlled bursts can help maintain accuracy, especially at longer ranges.
