Fallout New Vegas - Honest Hearts
Upon arrival in Zion you are ambushed by a tribal gang called the White Legs. After killing them I looted various weapons & items I needed before checking my map to find a nice big world map. Lots of exploring to do & locations to find.
The scenery is set like the Zion National Park in Utah http://www.nps.gov/zion/index.htm lots of big cliffs & ridges & flowing streams.
You are given a companion Follows-Chalk straight away after you have taken care of the White Legs attack, very useful for helping you carry the extra loot.
I like that this DLC let's you use the fast travel on the map markers & sleep at any beds you find unlike Dead Money.
Your companion leads you to Joshua Graham who seems to play a big role in this DLC. You learn a bit about him from the caravan merchant at the start of the DLC. He sends you on a fetch & retrieval quest which gives you a perfect opportunity to explore the area & also run into some Giant Geckos !!
