This is quite interesting why story mode is not online only. this is like an online game like lord of the rings online. but then its not free.
I know you really want Dead Frontier 2 trainer. But, that game is still in Early Access state. And, Early Access games mostly have ridiculous patch & update schedule (Liker, 2 times per day, in the history). That's why CH team refuse to do the trainer, right now. Cause it's very hard to maintain the trainer update to follow the game version.
And, I don't think it's a good idea, to be sarcastic in other game board post, because that game similar to Dead Frontier 2, but getting the trainer.
