"Like the original Perfect Dark, Goldeneye's three best maps – Temple, Facility and Complex – are included, but this time out there's a special bonus; Goldeneye's weapon set is also being included, meaning that for all intents and purposes the game has finally made it to Microsoft's console."

Sounds great! This'll be awesome when it releases next month!
