Is there a way to play offline? (without login)

Since there's no multiplayer anyway, is there any way to play completely offline?

I realize that the legit game checks if you've been online once every 30 days, but right now, since you need to log into ZClient, you need to have a connection every time you open the game.
 

Regardless, thank you for providing a way to play the game.

Without login - no, but zclient can be disconnected after game run, i fixed modules for this.
