In Counter-Strike: Global Offensive (CS:GO), there are three maps that are particularly loved by players, so they are called the "three old maps". These three maps are: Purgatory Town, Desert Lost City and Scorching Sand City II. Over the years, these three maps have always maintained a very high appearance rate. No matter how players adjust their map pool settings, these three maps will always be one of the most likely to be selected. The following is a detailed introduction to these three maps:
Purgatory Town is a map full of mysterious atmosphere. Here is what it looks like in the game.
Lost City provides a vast desert environment where players can enjoy shooting fun.
Hot Sand City II is a map full of tropical style, bringing players a completely different combat experience.
The above is a detailed introduction to the so-called "old three pictures" in CS:GO. I hope it will be helpful to you.
