The first Mass Effect game revolves around Commander Shepard and his quest to hunt down Saren and Sovereign to save the galaxy from destruction. However, the protagonist doesn't spend all of their time on a single quest. Alongside the game's main missions is an abundance of assignments for players to complete, all of which are included in the Mass Effect Legendary Edition.

The side quests focus on other happenings in the galaxy, which Shepard needs to sort out. Some of the assignments can be a little repetitive, but plenty of others are worth playing. Here is a collection of quests that no player should skip.

10 Garrus: Find Dr. Saleon

Loyalty missions don't exist in the original game, but some assignments relate to specific companions. For instance, the search for Dr. Saleon concerns perhaps the best squadmate, Garrus. Dr. Saleon, aka Dr. Heart, is a cruel Salarian who used to clone organs inside his patients' bodies to sell, often causing complications for the victims. When he was a part of C-Sec, Garrus tried to stop the evil physician, but Saleon slipped away.

If Shepard talks to the Turian enough throughout the game, he'll tell the tale of Dr. Saleon and give the Commander coordinates to find the villain. The action in the assignment is limited, yet the compelling backstory makes up for it. Plus, it's always nice to see great characters like Garrus get some spotlight.

9 UNC: Missing Marines

Relatively early in the game, Shepard can speak with Admiral Kahoku, who sends him on an assignment to find his missing marines. At the last known coordinates of Kahoku's team, the player finds only dead bodies and a huge Thresher Maw.

In the original game, fighting the giant monster wasn't too interesting. Yet, the Legendary Edition has made several exciting alterations to Thresher Maw battles. Maws now have sensory tentacles that players must shoot to get it out of hiding, which adds more variety to fights. Furthermore, their aim is incredible as they predict the Mako's movements, making their acid spit much harder to dodge.

8 Noveria: Espionage

Not every assignment in Mass Effect is about violence. In 'Noveria: Espionage,' Shepard has to keep Rafael Vargas talking while a device hacks into his personal network.

To please the Asari who gave Shepard the job, the player has to convince Vargas that they're genuinely interested in buying something from Binary Helix. Since this is Mass Effect, there are multiple ways for the quest to play out, partially based on whether Shepard is Paragon or Renegade. It all makes for a unique and compelling assignment that players can find near the Hotel bar on Noveria.

7 Citadel: The Fan

Despite featuring sparingly in the trilogy, Conrad Verner is a memorable character. He's a fanatic of Shepard's, desperate to follow in his hero's footsteps. At different points during the first game, he'll be waiting down in the Citadel markets.

As part of 'Citadel: The Fan,' the Commander has several conversations with Verner. During each talk, Verner's enthusiasm and delusion is funny to watch. Shepard's reaction to their number one fan is always entertaining, regardless of the protagonist's moral alignment.

6 UNC: Geth Incursions (aka Geth Activities)

The Geth are among the most powerful races in the Mass Effect universe, so Admiral Hackett is understandably concerned that they have multiple outposts in the Armstrong Nebula. As usual, it's up to Shepard to put an end to the Synthetics' activities. The Commander must go around to each outpost and destroy the Geth forces waiting there.

The enjoyment of this assignment depends on players' feelings about the new Mako, as it features heavily in the mission. However, the main reason to do this quest is the important terminal at the final base. Shepard can give the data retrieved from this terminal to Tali, which will strengthen their relationship.

5 UNC: Rogue VI

'UNC: Rogue VI' is an assignment given to the player by Hackett. The Alliance Admiral asks Shepard to go to Earth's moon and destroy the out-of-control VI that's taken over Luna Base. During the mission, the Commander and their team shoot through an abundance of flying drones.

As players spend most of the story facing Geth or Krogan, the drones are a nice change of pace. The real reason to complete this quest, though, is because it rewards the player with a Class Specialization. If players choose the right Specialization, it can make them significantly stronger.

4 UNC: Cerberus

Players might not remember that Cerberus is barely involved in the first game's adventures. However, in the rest of the Legendary Edition, the morally questionable organization plays a significant part in the story. In fact, Mass Effect 2 feels a little weird without knowing why people hate the Illusive Man's crew.

Admiral Kahoku gives players the chance to learn about the group, tasking them with investigating a few of their research facilities as part of the 'UNC: Cerberus' assignment. During the lengthy mission, Shepard finds out some horrifying information, helping flesh out the story.

3 Wrex: Family Armor

If players want to hear Wrex deliver great lines throughout the entire trilogy, they should do his family armor quest. Completing this assignment isn't the only way to keep this Krogan alive, but it is the easiest.

To acquire the mission, Shepard has to regularly talk with Wrex on the Normandy until he reveals that his family armor is in the hands of a Turian pirate. During the assignment, players will storm the base of the trophy hunter and attempt to kill plenty of his people in an entertaining battle.

2 Virmire: Assisting Kirrahe's Team

Shortly after arriving on Virmire, Shepard will meet a Salarian captain named Kirrahe. It doesn't take the leader long to become popular with players, as he's a very likable character.

During the assault on Saren's base, the Commander can help the charismatic Captain stay alive. To do so, players have to complete 'Virmire: Assisting Kirrahe's Team'. The objective to destroy the Geth flyers is the one that really matters, but it's worth completing the entire assignment, as it's enjoyable to help out allies.

1 X57: Bring Down the Sky

Originally, Bring Down the Sky was an expansion for the first game, but now it's included as part of the Legendary Edition. The main quest is a lot longer than a typical assignment, and it sees Shepard attempt to stop a group of Batarians from destroying a colony named Terra Nova.

New enemies, fun action, and a solid story make the Bring Down The Sky assignment one of the best. In fact, if it had more connection to Saren or Sovereign, it would feel more like a main mission as opposed to side content.
