I've been an Xmen owner since 1.0 code. I thought it shot well and the code was ok. Didn't mind 1.13 code and then 1.23 happened for about 5 games before I reverted back to 1.13. I didn't update until I think 1.3 then I'm sitting at 1.5 and haven't bothered with 1.51.
Xmen is a great game! It shoots nicely it isn't a total wood chop fest like they're making it out to be and teach more I enjoy. I like Phoenix mode because you start her and you can finish her multiple ways. 1 shot Phoenix twice, shot cyclops 4x, shoot wolverine 8x or a combination of the about to equal "8" shots (Phoenix worth 4x, Cyclops 2x and Wilbur 1x). Pro. X is a great mode too where you've got to know what character is which switch. Don't know it hit pro. X again and he'll tell you where to shoot with a light. Pretty damn cool mode imo!
I've never been to danger room or dark Phoenix but I still really enjoy playing the game. The call outs don't get to me and it's outlasted SM, shadow, and a whole big list of other games. Enjoy the call outs for what they are (crap and a bit of fun) as they're truely Xmen written lines.
Oh and the start to magneto multiball is EPIC! And so is the multiball rules! Shots are worth more damage to magneto if you've started a hero mode than not it's pretty damn cool rule set.
Do yourself a favour and pick one up for 5k it's pretty damn fun. I know mine won't be going anywhere.
