Superheroes work better when they work together against the world's evil supervillains. But not everyone ends up on the same team. And while these teams share the goal of trying to defeat the supervillain, they sometimes still compete with each other over who will deliver the final blow.

The Blue Team expansion for Marvel United introduces Team vs. Team mode. In this game format, players are divided into two teams of two or three players each (which means up to six players can play at a time). They're both trying to defeat the supervillain, but they're also competing against each other for the glory of bringing in the villain. In this case, it's Mister Sinister trying to steal genetic material for his nefarious means from across the city. .
