Crossing the line of fire is a large-scale online game owned by Tencent. Unconsciously, CF has been with us for ten years, and I have been playing since primary school. I still remember when I went to the Internet cafe in elementary school, and when I saw someone playing crossing the line of fire, I asked how to play. He registered a QQ number for me, and since then I have become a CFer. At that time, the most fun thing for CF was to play biochemical mode. I got a cannon, and then I went to the biochemical pyramid to kill zombies. A cannon can score 400 points. Later, after entering junior high school, there was a challenge mode. In order to open a golden RPK, we began to organize a group to brush the challenge. Although I'm at work now, I still play a few cf occasionally when I'm bored. I feel that there have been three maps since I started playing CF, namely the biochemical pyramid, the transport ship and the New Year Square. Let's briefly introduce them.

First, the biochemical pyramid. The Biochemical Pyramid was the first map I came into contact with playing CF. At that time, we were all primary school students, so it was best to play m4a 1, but I was really happy at that time. Later, after I started to brush the challenge, I began to fight with some good weapons, such as air hammer, gold RPK, silver killer and so on.

Second, the transport ship. The transport ship is also an old map. I still remember that at that time, I could get stuck on a transport ship and watch the plane, and the sea was all off the map. It was very popular at that time to be intercepted diagonally on a transport ship, which was very exciting.

Third, New Year Square. New Year Square is also an old map. When I want to play blasting, I will play several New Year squares. This map is very technical. Generally, when I fight security guards, I keep the middle door, and few enemies can cross it. My sniper level is still very good, but it's a little poor now.

Ladies and gentlemen, do you know which map has the longest history of crossing the line of fire? what do you think? Welcome positive comments.
