.30.A3. Project Firewalker: Volcano Station

First things first, you need to head over to the Caleston Rift, specifically the Yakawa system. Once you're there, your main objective is to make your way to the Research Station. The route is pretty straightforward, almost like a straight line.

You'll see plenty of iridium deposits along the way – there are about 8 of them. If you want to mine them, go for it! Just know that the two deposits at the very bottom only give you 250 iridium each, so don't expect a huge haul from those specific ones. Keep following these deposits, and you'll eventually spot the entrance to the Research Base.

Once you reach the base, you'll need to get out of your vehicle and head inside on foot to do some investigating. Inside, you'll find a few things to loot: a wall safe in the northwest corner (it's got 250 credits), and a locker in the room where the sensor is (that one has 125 credits). There's also some iridium stashed behind the bypass door. Seems like those scientists weren't exactly rolling in cash, but they left some loot behind!

After you've grabbed what you can, go ahead and activate the Sensor. This will kick off an event, and your next task is to get out of the base. Don't stress about a timer here; you've got all the time you need to make your escape.

Once you're safely outside, hop back into your Hammerhead vehicle. You'll need to drive through a few tunnels. Again, no need to rush, as there's no time limit. The main thing you'll notice is the screen shaking, but there aren't any hidden surprises. Just focus on navigating through the tunnels and jumping your way to safety. Keep an eye out, as there's another iridium deposit on your way out.

Finishing this mission should automatically unlock the next one in the Firewalker series: 'Firewalker: Prothean Ruin'.
