At first I was really hesitant about buying cheats from SystemCheats because most P2C cheats get detected really fast for one and for two finding a DBD cheat has been kind of hard to do. After lurking for about a week I decided to try the one day DBD trial to test and I was really impressed.
The loader works flawlessly, is super fast and responsive. you have the option to auto sign in and auto load as well. after picking your cheat you simply click load cheat and once its prompts you to load the game your pretty much done. once in game and the menu is loaded you will many options for the cheat and for being external it works great. I even recommended it to a few of my friends now as well. DBD had never been so much more fun. 10/10 on this cheat.
Haven't t had to use support but from what I have seen the staff is very responsive and updates are quick. Definitely recommend getting this cheat and using SystemCheats services.
