Tales from the Borderlands

There really isn't much to explain for getting any of these achievements. All you need to do is complete the story. Nothing can be missed and no wrong decisions can be made, so you are able to tailor the experience to your preference. To get the full experience, you should investigate everything, or to speed through you can simply go to the proper objective.

The only thing worth noting is that you'll have to be quick in some of the action sequences, flicking the thumb stick in the proper direction, hovering over the proper item to select it, or mashing the proper button quickly. I never failed a sequence in my playthrough though, so it's really not that hard. The game will tell you what to do at all times with on-screen prompts, including when to use Rhys' echo eye ability.
