SSV Normandy
- The SSV Normandy SR-1 serves as Commander Shepard's primary mobile base and hub throughout the game. Players use the ship's Galaxy Map to navigate between star systems and interact with their squadmates between story missions. It also provides access to equipment management, armory purchases, and the M35 Mako deployment bay.
Enemies
| Enemies | Weak to | Steal / drop | |
|---|---|---|---|
| Geth Trooper | Standard synthetic infantry unit armed with assault rifles; easily dispatched with tech abilities and basic weapon fire. | ||
| Geth Shock Trooper | Tougher geth variant that deploys Barrier; utilizes Carnage attacks with its shotgun that deal heavy burst damage. | ||
| Geth Recon Drone | Floating automated drones that fire rapid energy bursts; weak hull makes them vulnerable to rapid fire and tech attacks. | ||
| Husk | Melee cybernetic zombies that sprint toward your squad; they emit an electrical area-of-effect discharge on death, so keep them at a distance. |
Tips
- •Use the Marksman pistol ability early on, as starting weapons overheat rapidly and Marksman drastically boosts accuracy and firing rate.
- •Keep squadmates in cover with directional commands when approaching geth snipers perched atop the ridges near the research shelters.
- •Talk to all companion squadmates on the ship after every major story planet to advance their personal dialogue trees and unlock companion-specific assignments like Garrus: Find Dr. Saleon and Wrex: Family Armor.
- •You can use the galaxy map console located directly behind Joker in the cockpit to plot courses, select mission destinations, and land on uncharted worlds.
- •Inspect the M35 Mako in the lower Engineering bay before landing on hostile worlds to make sure your party's weapons and gear are fully optimized for ground combat.

The full walkthrough text
Shepard investigates an attack on the human colony of Eden Prime, uncovering a Prothean beacon and the betrayal of rogue Spectre Saren.
1. Normandy Briefing
You begin standing behind Jeff "Joker" Moreau and Navigator Charles Pressly in the SSV Normandy SR-1's Cockpit and Bridge as they argue about Nihlus Kryik. Walk down the corridor to the Comm Room briefing area to meet with Captain David Anderson and Nihlus to learn about your covert shakedown run in the Utopia System of the Exodus Cluster. After the mission briefing concludes, prepare to deploy to Eden Prime.
Tip: Talk to your crewmates before leaving the briefing area to get early context on your team.
2. Drop Point Ravine & First Rise
When you touch down in the lush drop point ravine alongside Staff Lieutenant Kaidan Alenko and Corporal Richard L. Jenkins, loot the nearby containers before moving uphill. As you proceed to the first rise, Jenkins charges ahead recklessly and is ambushed and killed by Geth Recon Drones. Use Kaidan's Overload and other tech powers alongside concentrated assault rifle fire to bring down the floating probes and collect your baseline starting gear and level-ups.
Tip: Target the Recon Drones with tech powers immediately to shred their light barriers quickly.
3. The Clearing & Dig Site 2
Advance past the ambush point into the clearing where Gunnery Chief Ashley Williams is fleeing from attacking Geth Troopers. Take cover and suppress the troopers using Overload, Sabotage, and Throw, then choose supportive dialogue to gain Paragon points or a dismissive response for Renegade points as Ashley joins your squad. Continue onward to Dig Site 2, where you will discover an excavation trench crater from which the Prothean beacon has already been removed, along with nearby supply crates.
Tip: Keep to cover on higher difficulties and use biotic Throw or tech abilities to neutralize trooper shields.
4. Research Camp & Shelter Encounter
Push into the research camp clearing where colonial victims are impaled on Dragon's Teeth spikes and morph into Husks. Keep your distance from the charging Husks and knock them back with biotics such as Throw, Lift, and Push before they can trigger their shield-stripping electrical EMP blasts. Afterwards, unlock the research shelters to search the containers and speak with Dr. Warren and Manuel; you can either hear Manuel out for Paragon points or knock him out cold for Renegade points.
Tip: Use crowd-control biotic powers like Push or Lift immediately to halt sprinting Husks before they reach your squad.
5. Train Station Tram & Powell's Interrogation
Proceed toward the cargo tram platform, where you witness Nihlus Kryik being betrayed and shot dead by Spectre Saren Arterius. Deal with the aggressive Geth Shock Troopers and Destroyers by coordinating Kaidan's Sabotage and Overload to strip shields and overheat their heavy weapons. Before interacting with the tram console, locate the dock worker Powell hiding behind cargo crates and interrogate him using Charm or Intimidate to make him surrender his hidden cache of grenades.
Tip: Overheat the weapons of incoming Destroyers with Sabotage to blunt their dangerous shotgun pushes.
6. Spaceport Demolition & The Prothean Beacon
Ride the monorail tram to the spaceport platform, where you witness the Reaper Sovereign taking flight while geth forces arm four demolition charges across the depot walkways. Sweep along the circular walkways to eliminate geth troopers, snipers, and combat drones, manually interacting with all four demolition terminals before the active countdown timer causes mission failure. Once all four bombs are disarmed and the perimeter edge crates are looted, interact with the excavated Prothean beacon to trigger the vision cutscene and finish the prologue.
Tip: Sprint between circular ramps to prioritize disarming the four demolition terminals before clearing remaining geth snipers.
The short version
What matters
- Disarming all four demolition charges at the spaceport railway depot before the mission countdown timer expires.
- Opening every upgrade kit, aid station, and crate across the mission route using decryption, hacking, or Omni-Gel for early weapons, mods, and med-gel.
- Using Charm or Intimidate on the hidden dock worker Powell to uncover his concealed grenade cache.
- Managing squad biotic and tech abilities to strip geth shields and keep sprinting Husks at bay.
Common mistakes
- Boarding the cargo tram console or touching the Prothean beacon before thoroughly looting every nearby container, which permanently locks out missed gear.
- Allowing charging Husks to get within melee range, which detonates an electrical EMP blast that instantly vaporizes your shields.
- Focusing exclusively on picking off distant geth snipers during the final battle while ignoring the ticking demolition charge timer, resulting in an instant mission failure.
