| odd, i seem to remember answering a question similar to this one already in another thread but, whatever. After you blow up the cordite, switch to your thermal visor and look at what was behind the cordite. You should see a source of heat coming from a small box, itll look redish orange, shoot that with your wave beam. thatll charge up the door and unlock it. youll have to do that several more times throughout the game. if you scan a door, and is says that there should be a consol of some sort near by to charge it up, always switch over to thermal vision and look for those small sources of heat
im pretty sure youll get the spiderball after fighting Thardus. hes in the phendrana drifts | |
