So checked out Scorchers, its $5/400 msp out next week, dang was hoping it would be free on PC. Maybe it will be on sale for Steam Winter Sale, usually brand new DLC isn't, but this is 15 months after game launched and its not called Skyrim.
It doesn't say that it adds any co-op, so thats a bummer.
Lets you play beyond the ending, thats good for finishing up loose ends.
