Eliminating Plateon

You've returned. Did the Plateon give you any trouble? Doesn't look like it. And you got the Plateon's Helmet, too. HQ will definitely accept this as another completed mission. They sent this over for you!

I keep getting new tasks thrown at me from the Sector, and I'm busy beyond belief as a result. I've been actually waiting for your arrival. The news is, the aliens threatening the Sector now are much more powerful than the Mateon that you've previously faced.

The alien in question is Plateon, and they are much higher ranked than Mateon, with the power to show for. What do you think? These may be much tougher than you've ever faced off against, but... will you do the honor of defeating each and every one of them?

Did you get the 50 Orange Juices? This mission sure is more difficult that the last one, but I'm sure you had an easy time completing it. There are still some missions left from the Sector, so whenever you have time, please talk to me, alright?

I knew you'd accept! Can you take care of the Plateon aliens around the field and bring back their helmets? I don't want the aliens reusing any gear we can get away from them. I should be able to report back to HQ once you bring back 50 Plateon's Helmet items. Good luck!

I don't think this would necessarily do you any harm. If you have a change of heart, please talk to me. Until then, if you'll excuse me...

It seems like you still haven't completed the mission from HQ. Take care of the Plateon aliens that threaten Omega Sector and bring back 50 of their Plateon's Helmet items. They're stronger and more dangerous than the ones you fought before, so be careful!
