Omni-tool upgrades

I'm satisfied with the very first piece that came up when I searched, "Omni Tool" in this humble website.

There should be a Mass Effect, not a major installation as a sequel, but a side-story that follows Tali's lives in Rannoch.

I know that there's this whole thing about the ending that will make this complicated, but who wouldn't want to play a Harvest Moon, Quarian Style..?
