One of the best campaigns :)!!!!

I played this map with bots, but unfortunately with bots it is a bit difficult to pass it, in advanced realism, but if it can be achieved (but you are late), I will say that it was one of my most favorite campaigns because of the difficulty, texture, the background sounds, and the mechanics of the story, was really good, I congratulate you too much for creating this kind of campaigns that are worth gold !!!, I wish you the best and that in the future you do well being better :).

Amazing campaign

I played it and I could say that I liked it too much, both in the musical background, the texture, the appearance of the zombies of the left 4 dead 1 and that you use the survivors in that campaign, it could be said that I had a little inconvenience when playing , but the benefits of this campaign are greater, so in my case I hope a campaign that may be possible to pass but in the form of a challenge, that is to experience the pressure, and the emotion that everything goes well, you made a great job and thank you very much, keep it up !!! :)
