No One Escapes Alive Guide:
My setup was the Pack a punched' Tommy gun with Dead-shot Daquari. This kills the zombies quickly. Another idea would be to pack a punch a ray gun as it kills the guards in less than one clip.
You arrive on the bridge after flying on the plane. See Pop Goes the Weasel for more details on building the plane. For this you will ideally need great pack a punched weapons or wonder weapons with a good amount of ammo, and possibly the hells retriever to be able to survive, also depending on skill. On round 14 with a couple of zombies left, get any coop partners and head out on the plane. When you land on the bridge, kill the last couple of zombies and prepare for the next round. Survive this round to get the trophy. Do not go near the electric chairs, as they teleport you back to the prison! This can be done on any round after 15, but they obviously get harder as you advance the rounds.
This requires you to first build the plane (see "No One Escapes Alive") and then use it to go to the Golden Gate Bridge. Make sure you only have a couple zombies left when you go to the bridge on whatever round you are on.
You will want to have at least one Pack-a-Punched weapon and the Hell's Retriever to make this easy. It is very close quarters and there are several Warden's that will spawn in. Remember to aim for the head and you should survive. Stay away from the electric chairs until the round is over!
