Alright, has anyone ever noticed those two holes in the fences in the backyards? Well if you have and tried to go prone in them that wont do anything! What you need to do is get an RC-XD car and drive it through the hole. Once you are out then follow the trail and when you get to the rock "ramp" hold the boost (left trigger)and you will make it over to the other side and into the other backyard. If you would like to try this out i would reccomend going into a private match and set the RC-XD car so it doesnt detonate automattically. If you find this cool dont stop there, in every multiplayer map there are multiple tunnels just for the RC-XD. I found alot of them and they are really fun to explore. Enjoy! :)
