i think they definitely re-textured the playable characters in some way but I'm not sure if it's MUA 2 assets or not. I remember Hulk having a square head on Xbox 360 for sure. It's a very low effort port and should of been cheaper and should of just been called a release at launch. It's like the Ghostbusters remaster where nothing really is changed accept minuscule things.

Because Nick is playable I guess but that's not excuse devs in my opinion. Thanks for the screen, I guess I should refresh my knowledge on topic.

I wonder why Black Widow is low because if you notice in your shot, Nick's arm is detailed.

I thought Deadpool and Iron Man always looked like that. Here is a 360 shot. https://www.gamespot.com/a/uploads/original/gamespot/images/2006/299/reviews/761257-932586_20061027_001.jpg

High-polygonal Deadpool vs stonecutted Black Widow

Well, Iron Man and Spidey clearly looks out of place. Default Iron Man suit looks so we'll detalised, so clean -- then you see square headed Hulk or Reed Richards with fingers glued together. I know I'm exaggerating right now, but IIRC that's how mod-makers in MUA community worked back in days.

What models from MUA 2 did they use? To me it looks like all they did was clean up the visuals a little bit and did nothing else. So basically no effort at all. It should of been called a release and not a remaster to be honest. An official PC version of the first X-Men Legends would be great since the sequel is already on PC.

Oh, what are I'm talking about, they will do exactly that.

I guess X-Men Legends deserve second chance too, but that's unlikely: they can't pull that trick like they did with MUA and just steal some character models from MUA2 and call it "remaster".
