Goldeneye 007 for the Nintendo DS. what do they mean by remake?

It's a complete remake. The first mission (The Dam) You don't even go in by yourself. You have some random guy who has yet to be identified by Nintendo who comes with you on the mission. Not only that, you play as the New Bond (The Blond Bond) from the most recent movies (His name escapes me, sorry). Also, there appears to be different action sequences and you even get a rocket launcher in one of the Campaign Missions, something I never did in the Original Goldeneye.
