Notice for Lock-on System, Difficulty and OST DLC.

Dear all:
Some players said about the lock-on system. We will deal with it as soon as we can. We apologize for it.
The game maybe hard for someone not skilled in ACT games. Please choose the first difficulty or go to find some skills. That will be interesting when you know new way to beat the enemies.
Our original sound track is free for you and it will be downloaded automati. You can check on the contains dlc at page of this game in your library. And then, choose library --- music, maybe you can find our OST, if not, add tracks --- scan tracks. If still can't find it, restart your steam maybe it will be refresh.
Thanks very much!
