You can find this in Rockwell’s garden in Rockwell’s innerds go in as deep as you can where his heart is and final mission terminal directly below there will some stomach acid wait for it to go down then it’s everywhere on there ground pick it up by hand there’s heaps of it be careful for the stomach acid rising and the reaper queens but seeing how we all have a tek suit it’s quite easy
The map is a ship. When the ship goes into hyper drive, the space area (the large gap in the center of the map) changes resources. The color of drops also changes. Mutagel can be harvested in the space area when the drops are white. The rocks in space also have ambergris. The color of the rocks are an orange/bronze color. The area in space has greyish rocks with cyan looking flecks in it.
You can find this in “the void” on the Genesis 2 map. The Void is the space area in between the two half’s of the whole map. The easiest way to get there is to get a flyer and look really high on the ship wall and find a hole/duct.
You can only find it by harvesting a brown (turd like) rock on a certain day. You never know when that day is since the void changes every 24hrs.
