Am I just gonna play through the entirety of the main DMC4 campaign just with Vergil?
Why not? I was doing that last night and it was hella fun.
Vergil had a pretty good moveset in the reboot game, but by God he is so much more satisfying to use in DMC4SE.
This was a very uneventful E3. The only things there I care about are DMC5, the Resident Evil 2 remake, and Control.
Nothing really mind-blowing.
