Luigi's Mansion: Dark Moon has local multiplayer
Luigi's Mansion: Dark Moon has something its precursor didn't. According to the 3DS title's website, the sequel boasts "a brand new local multiplayer mode". Nobody's talking about what that means yet, but IGN has teased a reveal within the next few days. Luigi's Mansion: Dark Moon was recently dated for March 24 in the US.
