(adsbygoogle = window.adsbygoogle || []).push({}); I know both excavators have to breach both tunnel 6 and 11 but I think there is another way you can get it by leaving one path closed and the other breached by the excavator so go back to the receiving area at the beggining then kill yourself by jumping off outside or let the zombie kill you. Make sure you leave one door closed let the others finish the round respawn and you should get the achievement. If your wondering how to get back to the beggining without opening the door that isn't breached let the astronaut grab you and then you teleport near the receiving area or use the gersch device if you won't want the astronaut stealing your perks :y:

Doing this will also activate the song Nightmare by A7X (Avenged Sevenfold). Great song. I got it on my Ipod.

I love that song :y:
So how do you exactly get it to play? cos i never know it just comes on randomly :p

You must do the One Giant Leap trophy (or achievement on 360). When you do it, the song will play. If you already have the trophy (or achievement) then just do what you would have to to get the trophy again (in a different game) to play it.

nice one mate been trying to do this

Thanks finally got the trophy

Thanks for this matee!
