First and foremost: I love the game. I absolutely adore it.
But the DLC didn't really give me the experience I hoped for. As someone who already beat the game 100% and is lvl 99 there was no difficulty in beating the arenas (which all looked very same) and gathering all the rewards. I also find that the 9S part was as boring to play as his playthrough.
The "secret bosses" were cool though and the costumes and masks look very nice (I love A2's outfit) but the hair colors feel off for me. I don't think anyone of them fits very well (besides light blue maybe).
At a price point of 14€ I expected some more late game content since the arenas were awfully easy and the special difficulty and highscore beating ranks at the end are not worth playing. Either you won't get any special rewards or it is ridiculously difficult just for the sake of being difficult (lvl 130 enemies and one hit death, wth).
I think as an addition to a normal playthrough the arenas might be a good addition to come back to once in a while but playing the DLC after beating the game is kind of pointless since all you can do with your outfits and new hair colors is run around and one hit robots.
What do you guys think?
