As it would seem, I have finally passed hard mode. The last fight was only a bit harder than in normal mode, which shows that my skill has increased. As I started Dante Must Die mode, I have come to realize that either I have no skill, or the enemies have increased there aggressive behavior by about 500%. They now attack me in groups and it only takes about 7- 10 hits to kill me from one of them. I will have to try out many different skills to win this, patience maybe key, as well as staying alert and quick reflexes.
