The Strider is a towering biomechanical war machine used by the Combine in Half-Life 2. Standing over 15 meters tall, it moves with terrifying speed and agility despite its size, using its three long, insect-like legs. Striders are heavily armored and equipped with a devastating pulse cannon and a powerful warp cannon capable of annihilating enemy forces and structures alike. Their eerie, organic appearance combined with advanced alien technology makes them one of the most memorable and intimidating enemies in the series. Encountering a Strider usually signals a high-stakes battle, requiring quick thinking and heavy firepower to bring it down.
