Shooting games share a simple premise: aim, fire and survive. Beyond that, the category is surprisingly broad. There are space shooters where you thread through patterns of enemy bullets, top-down games in which you fight off swarms from every side, target-practice games that test accuracy and speed, and first-person shooters that put you behind the sights. The genre grew from early arcade games in which a lone ship fought off descending invaders, and developers have been finding new twists on it ever since. Most games are built around escalating waves, higher scores and upgrades that let you take on tougher opponents, which gives them a natural pull to try again. Skill improves with repetition, as you learn enemy patterns and become better at positioning. All of these games load and play on GamesClips. If you enjoy fast reflexes and a steady aim, pick a game and start firing.
