if u can find how we get the green matrix shard at corellia and where exactly..
You get to it through the starship museum on Axial Park. take the elevator up, get on the roof, jump off the roof to a lower roof to the east, run around that roof until you see a blue shiny across the plaza for your MGGS, then you grappel over and go in the building and run for a while to get it. The problem is the MGGS is buggy and you may die. Try to fire the MGGS and then fire it a second tiem as the rope is shooting out to make it across. It's really wonky though, took me 50+ tries to time it right.
