An action game is a genre of video games that emphasizes physical challenges, rapid reflexes and skillful timing in order to progress. These types of games often involve combat or fast-paced activities where the player must use their keyboard, mouse or controller to perform various actions such as jumping, running, shooting, punching or driving. The goal is usually to complete levels by overcoming obstacles and defeating enemies while collecting power-ups and upgrades along the way. Examples of action games include first person shooters like Call of Duty, platformers like Mario, beat 'em ups like Streets of Rage or fighting games like Mortal Kombat.
