One of the best trainers I've used in nearly any game. Active and helpful developers are constantly updating/fixing the trainer, and downtime for updates never lasts more than a few days, where they even compensate you for the time lost by adding extra time to your license. Trainer has so many unique features that separate it from the rest, and allows you to do anything you wish in the game, from playing subtly with a little speed boost and some ESP to full on raging and instantly killing all survivors with the press of a button. Price is very fair for what you're getting, and with more updates coming out often, it only gets better.
