This feels like an expansion...
The graphics are the same as the first game which are still excellent. The new locations all look fantastic but there's a little too much repetitiveness in some locations.
The music is still good as well. There's no complaining there.
The gameplay is exactly the same, except you can unlock stuff by doing optional quests that opens up as you finish level. You can also revisit locations if you need to pump up your character more. This game is not a cakewalk but the final boss was extremely easy to beat.
The online component has been improved but it's pretty much the same as in Champions.
Like i said before, this game felt like an expansion and i pretty much rushed the game and never looked back once i finished it. There's so much Hack and Slash i can stand even if it's well done.
