From the shuttle area you're now in, head right and save your progress before heading out right once again where you'll be met by a green plasma door. You can't blow these open until we get our next upgrade so start bombing the floor and you'll find a way down. Bomb the floor again to uncover a launcher and hop in to reach further into the area.
You're going to come across a new enemy type here, X Parasites. They're a little trickier to kill, parry works great for the larger ground-based ones, but they also give you health and Aeion refills so make sure to take them out and grab these refills before they have time to regenerate into another enemy. Deal with these new foes and keep on following the natural route of this area until you arrive at the statue room we've pinpointed below. Congratulations, you've earned yourself the Plasma Beam.
