the campaign mode is a bit difficult for only one player,and enemy's weapon are better than you,you will often find that——what?why I have been stucked in the hill again? And you have to connect to the internet if you want to play,sometimes I just want to play offline,I hope it could be solved someday
Yes, there definitely should be an offline mode. As for campaign mode being difficult, this is a fairly common complaint. You'll just have to level up through multiplayer so you're stronger.
