In the context of video games, "leaching" is a term used to describe a specific gameplay tactic or strategy in which a player exploits a particular game mechanic to gain an unfair advantage or farm resources without engaging in legitimate gameplay. In Contra III: The Alien Wars, leaching typically refers to staying in a safe spot on the screen or exploiting enemy behavior to accumulate power-ups, points, or extra lives without actively progressing through the level or facing significant challenges. Leaching is often considered an unsportsmanlike approach and detracts from the intended gameplay experience.
