We're not on oshuane to collect samples.

May be obvious to some, but i think the only reason we're on oshuane is to harvest E-711 to make dark fluid. Dark fluid of course being what turned meridia into a black hole. So we may be gathering it to test black hole weaponry. Maybe a new grenade/rocket launcher type to create a miniature black hole to suck in large groups of enemies slowing them down and pulling them in at the same time.

This would be good to combine with small aoe strategems or group a lot of enemies together to drop a 500kg bomb in the center. Of course, it would be harder to effect larger ones such as chargers, bile titans, flesh mobs, tripods, hulks, and larger. Anyways, this is my theory that we may be getting black hole weaponry within the coming weeks or months.
