Thanks snail & ladd for the formal responses, appreciate it sirs. That's a bust though, wonder why they even bothered including them as online challenges as there's some hall of meats that are in single player but not multiplayer, so with that said why they left that one where a ramp is an absolute must or you can't do the challenge is beyond me, super rushed an unpolished. Anybody happen to figure out how to complete the one where you have to air into the tunnel and then launch yourself into the billboard?
