If it's an FPS with large maps and large battlefields with many players

High intensity tactics
CQB games simulate realistic indoor close quarters combat, so the game maps are relatively not particularly large and are more three-dimensional rather than flat. For example, the maps in the R6 games are dominated by buildings, and the complexity of the terrain highlights the importance of tactics, so both ZERO HOUR and R6 are tactics-based FPS games. In FPS games, tactical time and combat time make up the entire gameplay experience of the player. So long tactical times inevitably lead to shorter combat times, as in Armed Assault 3 where it is often half an hour of tactical planning and execution and ten minutes of shooting and fighting.
