Challenge lobbies are much harder to do but I can host them but make sure you're on the prestige you want! If not, I can host a pick-a-prestige lobby (1-11, level 70) but I'm only hosting one if more than one person wants to be a different prestige before being in the challenge lobby.

INFECTIONS INCLUDE:
3 guns / gold deagle
unlimited ammo
laser from gun
super jump
and many more!

The infection lobbies will be hosted on Global Thermonuclear War!

To get the XP from the XP lobby, make sure you aren't level 70. Then grenade yourself and you'll be 70 (unlimited XP) [use one of default classes]. You can keep backing out and joining my session in progress to get to the 10th prestige, level 70.

To get in, all you have to do is subscribe to [ Register or Signin to view external links. ] and [ Register or Signin to view external links. ] (on YT obviously), send NAT 2 Reflex a message that says "12 FINGERED BONER RUBBING ESKIMOS" (on XBOX 360) and leave a reply to this post with your YouTube channel name so I can make sure you subscribed. Please don't leave any comments on my channel or videos or you won't get invited!

After you get your infections/XP, I'm not even requiring you to say "LEGIT" in a post. Just here to help you guys out!
