DLC #51 - Fallout : New Vegas - Old World Blues

Outsmart Dr. Klein, and escape Big Mountain

After the step up in difficulty bought about by Lonesome Road, Old World Blues follows up with a more relaxed set of trophies, more similar to the progression based nature of Honest Hearts.
                                                      
Out of the 5 trophies, 4 of them are all related to the main quest-line, which can easily be completed within 2-3 hours, and provides a very minimal challenge, despite 2 boss fights near the end. 
                                                     
Apart from that, the "Making Friends" trophy is the only trophy that branches away from the main quest, and puts you through a bog standard fetch mission, as you locate 10 pieces of data to re-activate 10 different electrical items in the central hub of the map.
                                                                    
The whole package is an incredibly easy 5 trophies, and should take no longer than 4 hours to fully complete. The challenge presented is close to non-existent and you could easily sit down and finish it all in 1 casual sitting.
