Lacking big time. It's not as bad as titanfall as at least you're aware there is a story there but there is very little information in the game world. The narrative of the story missions often leave me wanting more and the ghost dialogue lines are very bland and boring. Peter Dinkalbot lines are forgettable. Even in borderlands the little robot friend is interesting. You don't interact with any npc's except vendors and there is not reason for my gaurdian to be searching for loot or the vault of glass. At least in borderlands you understand you are treasure hunters. Bungie needs to do better making the world more engaging and immersive. I like the game but want more story and immersion.
