Shooter game

Shooter video games, or shooters, are a subgenre of action video games where the focus is on the defeat of the character's enemies using ranged weapons given to the player. Usually these weapons are firearms or some other long-range weapons, and can be used in combination with other tools such as grenades for indirect offense, armor for additional defense, or accessories such as telescopic sights to modify the behavior of the weapons. A common resource found in many shooter games is ammunition, armor or health, or upgrades which augment the player character's weapons.

Shooter games test the player's spatial awareness, reflexes, and speed in both isolated single player or networked multiplayer environments. Shooter games encompass many subgenres that have the commonality of focusing on the actions of the avatar engaging in combat with a weapon against both code-driven NPC enemies or other avatars controlled by other players.

Subgenres

Shoot 'em up

Shoot 'em ups (also known as shmups) are a subgenre of shooters wherein the player may move, up, down, left or right around the screen, typically firing straight forward.

Shoot 'em ups share common gameplay, but are often categorized by viewpoint. This includes fixed shooters on fixed screens, such as Space Invaders and Galaxian; scrolling shooters that mainly scroll in a single direction, such as Xevious and Darius; top-down shooters (sometimes referred to as twin-stick shooters) where the levels are controlled from an overhead viewpoint, such as Bosconian and Time Pilot; rail shooters where player movement is automatically guided down a fixed forward-scrolling "rail", such as Buck Rogers: Planet of Zoom and Space Harrier; and isometric shooters which use an isometric perspective, such as Zaxxon and Viewpoint.
