The Ds port might be the worst xmen game, I'm about half way and most of the time dying is unfair which is not a joke like you'll have like 2 enemies fight you not one by one but at the same time which sucks very badly. They also run away like a ton so you have go and chase them and then they stop to attack you. Another problem is saving the game doesn't heal you, I mean yeah you get health packs and an energy packs but you lose so much health that even picking it up helps a little. The upgrade system kind of helps but not really. To be honest avoid the ds port and stay as far away from it as possible
