With the original route to the mainframe blocked off, Mace has to enter the Temple ship from the top and look for another way. Will he be able to stop the dastardly hacker and save at least some of the space cultists?
Question
At the end of the level, Eridium gets mentioned. This material got kinda famous after being heavily used in the plot and gameplay of Borderlands 2. I tried to research if it gets mentioned in any other game/movie/story, but Google is just so plastered with hits about Borderlands, that I didn't get anywhere. So, do you know if it's featured anywhere else?
