Mass Effect: Corsair

About

An unreleased spinoff in the Mass Effect series that got cancelled due to high production costs for the DS game cartridge.

The game would have been a combination of the games Privateer and Star Control set "in a part of the galaxy that was more piratey and not really fully explored", and the player would play as an independent character that explores, collects cargo, and sells information to the Human alliance.
