An "On-Rails Shooter" is a type of video game where players control a character or vehicle that moves along a fixed path. The gameplay focuses on shooting enemies and targets that appear on the screen while the player has limited control over movement. This genre often features fast-paced action and can include various settings, from futuristic landscapes to horror environments. These games typically use a first-person or third-person perspective, allowing players to aim and shoot at enemies. Popular examples of on-rails shooters include titles like House of the Dead and Time Crisis, which are often found in arcades and on gaming consoles.
