If your a Raze fan, and you need help, ask me as a comment or here. I've got LOTS of tips. Seriously. I know about good snipe spots, campaign help, what weapons you should use, strategies, and much more. Just ask my friends. (Shouldn't the creator of Raze do this? Yeah, I know. Don't comment about that.)
But, Abandonment is the area best for this. And, I don't like Base that much. It is useless fighting without getting any health. Still I get most of the kills and don't die even once.
