This was my first game I got on steam, I watched a few youtubers played it so when I found out it was free I instantly got it. The gameplay and mechanics work together so well. The gun play makes sense and the zombies work like zombies are suppose too. This is a must have for people who love a multiplayer zombie survival experience. Whether it is the survival or objective maps, and the people are nice too. But like most people I hate those damn kids they'll get you at least once and it won't be pleasant. Game still gets updates, with fun maps. But not a lot of people play survival maps, and some of the achievements are hard as heck to get. 10/10 will always download.
