I'm not quite sure if I will like this gamemode. It reminds me of Gunmaster. I hated that gamemode so much, it's so annoying to run into a dude who has Shotgun or automatic weapon and all you have is that crappy pistol. And obviously the same thing will happen in Scavenger. But, I think it's fun that you just have to adapt to whatever weapon you find. I hope they put a lot of different guns in there so there is a lot of variety.
I had a chance to kill the best, but then I remebered suicide is a sin.
