What is a Tank in the "Left 4 Dead" game?

The Tank is a special infected character from the video game series “Left 4 Dead.” It is considered one of the most powerful characters in the game and attacks by punching or throwing concrete slabs.

The Tank is extremely large with abnormal muscle growth and has a disproportional body frame that forces it to knuckle-walk like a gorilla. In competitive modes, gamers gain the ability to play as the Tank. It can take down an entire team of survivors, unless the team manages to defeat it. Survivors are allowed to defeat the Tank with various weapons, and setting it on fire helps deplete its health quickly.
