Not only has Sonic Generations for the 3DS received a batch of new screenshots, but there are also new information on the Street Pass functionalities: Among other things, you can exchange missions and profiles. Your profile cards contain information like how long you’ve been playing and what’s your favorite character, but that’s not the most important bit here.
Spotpass allows you to unlock 100 new campaign missions that aren’t playable otherwise and can be exchanged with other players. Don’t have any friends? Well, you can use those Gold coins you have been collecting all these months on your 3DS in order to unlock them. Pretty neat idea, but I hope the missions are worth it
