Tactical shooter is a sub-genre of first- and third-person shooters, associated with using strategy, planning, and tactics in gameplay, as well as the realistic simulations of ballistics, firearm mechanics, physics, stamina, and low time to kill. Dating back to strategy games from the late 1980s, the genre first rose to prominence in the late 1990s with the releases of several well-received tactical shooters. The popularity of the genre saw a decline in the late 2000s as fast-paced "arcade"-like action shooters rose to prominence, it has seen a revitalization since the mid-2010s with the successful releases of several modern tactical shooters.

A first-person shooter (FPS) is a video game centered on gun fighting and other weapon-based combat seen from a first-person perspective, with the player experiencing the action directly through the eyes of the main character. This genre shares multiple common traits with other shooter games, and in turn falls under the action games category. Since the genre's inception, advanced 3D and pseudo-3D graphics have proven fundamental to allow a reasonable level of immersion in the game world, and this type of game helped pushing technology progressively further, challenging hardware developers worldwide to introduce numerous innovations in the field of graphics processing units. Multiplayer gaming has been an integral part of the experience, and became even more prominent with the diffusion of internet connectivity in recent years.
