There are very few PVE based, sci-fi MMOFPS games out there. The last really good one was Tabula Rasa. I suppose that one other PVE one was okay (forgot the name, but it had a TV show. Defiance I think?)...but ewww Trion. And then the PvP only one Planetside 2. But Planetside 2 has no PVE at all.
This looks like it'll be amazing though! Very much looking forward to release. It reminds me of Tabula Rasa in some ways, but way better and more modern of course.
