Tired of playing the same old maps? Well, that's too bad, because Eurocom/Activision aren't releasing new maps.
However... Hackers are.
From what I've heard, there are unused maps stored in the games memory. A group of hackers (I prefer to call them heroes) are working hard at getting these NEW maps up and running and workable enough to play online. So if you run into maps with question mark thumbnails, they're probably brand new maps.
I've also seen videos of a map that's almost exactly the same as the Plant map from GE:R
I've gotten loads of information about these hacks from GameFaqs and thought that I could bring the good news here.
I'll try to update this thread with as much new info as possible!
