(To be honest, I never played the ME1 multiplayer, but the ME2 multiplayer was always fun. In ME1, it was known as the Shadow Broker DLC, and in ME2, it was known as the Liara System Hacking Mode. One of the most unique things about the series is that the multiplayer mode is integrated into the single-player. The Mass Effect series is known for its fantastic story and awesome characters. Thankfully, these terminals are all very close to one another (south and near the taxi stand), although hacking them may be a little tricky, so perhaps the video below can assist. You’ll need to start hacking different systems and terminals after a little more exploration and conversation (of which there are 3 in total). After conversing with Careena and arriving on the planet ‘Illium,’ you will discover about a woman named Liara T’Soni.
