Was thinking about buying this since they added rollback. I'm a beginner

Update Thanks to some help from other posters, I was able to unlock all the pictures in the gallery. While I am not sure of the unlock conditions for each picture, you should definitely unlock all of them if you do the following: Get all the achievements in the game; by doing so I had almost all the pictures unlocked Make sure that you clear survival mode (any difficulty) with Rock and Terry at least once In story mode, make sure that you fight Terry once when playing...

idk why the game need internet to work like i dont play too much online

All I need is a online match on the dotemu version of the game.

Anyone to do the online achievements?
