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.)
Nor the railgun, grenade launcher (Not sure, but yeah), and sniper (umm kinda).
Because the railgun fires so slowly and takes so long to reload, it's not much of a factor. Sniper is pretty deadly, yeah. Grenade launcher is too, I guess, but mostly only against the AI.
