left 4 dead 2

This is a fan version of Left 4 Dead 2! I don't claim copyright or anything! I just added it for fans and other players! I was looking for such a world but did not find it and decided to create it myself. if you liked it and you want more on other games, write in the comments. by the way, I recently got left 4 dead 2 and haven't played much of the game yet, but I will be grateful if you write the descriptions of the locations in the comments and I will add them to the world, also add your new locations, it will be very interesting. I learned that there is an opportunity to add java script code, and since I am learning web programming, I want to figure out how to add it correctly so that it works properly. if anyone has information on how to add java script better, please share it in the comments.
