Familiarizing yourself with the game and its mechanics is the biggest task for elite Call of Duty players. Little things like- moving, aiming and reloading are similar for almost all esports but require another level of focus in competitive play. To be good at the primary part, start playing offline and testing your skills. Once you get comfortable with the controls and maps, start playing online to experience better exposure to other players. Competitive CoD includes the following series- Black Ops, Modern Warfare, Ghosts, Advanced Warfare, Infinite Warfare, WW2, World at War etc. And, one can decide if he/ she wants to play in either a passive or aggressive manner. We highly suggest understanding the concept of the game before placing any type of bet online for real money.
