This Belongs in a (Different) Museum!
Look for a desperado outside a quarantined museum in Sakaar.
Talk to the man, then fly up around the building. There are four buttons, one on each side. Only two have landing platforms in front, though. Push those buttons.
For the other two, you'll have to mind-control the spiked guy inside. There are two pressure plates in there with him- each plate will extend a platform for one of the remaining buttons, so have him stand on one plate, fly out and activate that button, then do the same for the last one.
This will open the museum door, and let out the spiky one, but your mission isn't over.
Inside, you'll need to run the mini-lazer maze to shut down a forcefield, and claim the brick.
