Murray's Big Gamble

You'll start with Murray in front of a gate. Blast it open so he can move. Almost immediately, a Gorgeous Lou will pop out from the building ahead, and another will appear from the train car nearby. Keep an eye out for more dogs – one from the next train car, another from the building after that, and one more from the building after that. As Murray crosses the bridge, two more enemies will emerge from the garages, and then another will show up from behind the second building.

Once Murray reaches the second level, focus on a bulldog running through the first train car. Right after he clears the second train car, Gorgeous Lou will sprint out from behind it. Keep your aim steady; another Gorgeous Lou is hiding behind the building just ahead. Remember those toxic sludge barrels – avoid them! The next building is just like the previous one. When Murray crosses the bridge, he'll let you know he's halfway there.

Past the first garage on this section, you'll find another Gorgeous Lou. After you get by that, Murray will use a crane to get to the next level. Here, he'll face his first doberman. On the other side of the building, there's another Vinnie the Pincher. As Murray heads down the bridge ahead, he'll run into yet another Vinnie. Keep an eye on the rooftop above the next bridge; a guard is posted there. Finally, as you cross the last bridge, you'll encounter one last Vinnie the Pincher. Once he's down, the path to the key will be clear.
