Mass Effect 2: All Upgrade Locations

Mass Effect 2 is a game stuffed full of ways to improve your combat abilities. Each individual weapon has its own upgrade set, plus there are some for your teammates and ship. Some of these are essential to your success, whether in firefights or the actual story, so it’s crucial to know where each and everyone is. This guide will lead you to them!

How To Get Normandy Upgrades In Mass Effect 2

Med-Bay Upgrade – Mordin Recruitment Mission

You can unlock the med-bay upgrade after completing Mordin’s recruitment mission and adding him to your squad. Shepard will receive a message pertaining to the med-bay from Dr. Chakwas. It doesn’t impact the story of Mass Effect 2 but does allow you to heal your scars.

Thanix Cannon – Garrus

Garrus is always calibrating those engines, so it’s only fitting that he has a suggestion to improve the ship: huge Turian cannons that can be installed on the front of the Normandy. He comes up with this idea after Mordin joins the team. This upgrade does have an impact on the conclusion of Mass Effect 2, so you should consider investing in it.

Advanced Mineral Scanner – Miranda

Sick of meticulously scanning planets for resources? After Mordin joins the Normandy crew, Miranda will suggest a better version of the Mineral Scanner the next time you speak to her. It might not be essential, but it’s a godsend.

Heavy Ship Armour – Jacob

Once Mordin has been recruited, speaking to Jacob will prompt him to suggest better armor for the Normandy. Whether or not you unlock this upgrade will have an impact on the story of Mass Effect 2.

Multicore Shielding – Tali

Since Shepard crashlanded the original Normandy, you’ll probably jump at the opportunity when you speak to Tali and she suggests installing Multicore Shielding – after Mordin joins your team. As you’d expect, it does have an impact on the game’s conclusion.

 Modular Probe Bay – Thane

After Mordin gets on the ship, you can also speak to Thane and he will recommend a modular probe bay. It’s a non-essential bonus but it takes a lot of the annoyance out of probing by doubling your capacity.

Extended Fuel Cells – Samara/Morinth

Speaking to Samara (or Morinth) will prompt her to suggest bigger fuel cells for your ship, inspired by Mordin’s arrival onboard. It’s not important for the conclusion of Mass Effect 2 but is still useful.

How To Get Squad Member Upgrades In Mass Effect 2

Geth Shield – Tali Loyalty Mission

This Geth Shield upgrade is found during Tali’s loyalty mission, where she is on trial for treason. You’ll spend the first part of this mission on a ship called the Rayya before switching to a ship called the Alarei.

The first room contains Geth you’ll have to take down, but then you”ll progress down a hallway. There are several rooms off of the hallway before the next main segment. One is a medbay. The other is a small office. In the office, you’ll need to hack the monitor to earn this upgrade.

Geth Shield – Legion Loyalty Mission

During Legion’s loyalty mission you will traverse a base crawling with hostile Geth. Shepard can find the Geth Shield Boost during this mission once arriving in the Heretic Station Interior.

You’ll know that you’ve arrived at the right room because one Geth Hunter and two Geth Troopers will attack you and after you kill them the squadmate (that isn’t Legion) will ask how on the room outside the windows is. Legion replies that it’s probably more than 15 kilometers long.

The Geth Shield upgrade is available in this room by bypassing a Geth Terminal. If you reach the section where you are holding your position against waves of Geth, you’ve gone too far.

Krogan Vitality – Grunt Recruitment Mission

During Grunt’s recruitment mission, you can find one of his upgrades. You’ll begin at the research base’s outskirts, then approach and take out its defenses, before entering the base itself.

Shepard will meet Okeer and discuss their actions on Virmire from the previous games, then Okeer will demand that Shepard kill Jedore. Before you leave this room to do just that, hack the terminal nearby to unlock the Krogan Vitality upgrade.

Krogan Vitality – Mordin Loyalty Mission

Mordin’s loyalty mission involves his disturbing past working on the genophage. Once you’ve entered the hospital together, you’ll interact with the Clan Weyrlock Speaker before reaching a laboratory with research equipment and a dead Krogan woman in an off-shoot room. Interacting with her will prompt a conversation with Mordin about his research and regrets. Then, before leaving the room, hack the terminal here to earn your Krogan Vitality upgrade.

+20% Mordin Tech Damage – Mordin

This upgrade is fairly simple to acquire – when you talk to Mordin after recruiting him, there will be a prompt to ask Mordin about upgrades. He then provides this one for you to invest in.

+20% Jack Biotic Damage – Jack

You can speak to Jack about upgrades after Mordin has joined the crew. This will prompt her to give you this 20% upgrade to her damage.

How To Get Medical Upgrades In Mass Effect 2

+1 Medi-Gel Capacity – Mordin Recruitment Mission

This Medi-Gel upgrade is pretty easy to find. During Mordin’s recruitment mission, you’ll enter his clinic and spend a while chatting with him. It’s easy to get distracted, but don’t forget to find the research terminal to get your well-earned medi-gel upgrade before you exit the clinic.

+1 Medi-Gel Capacity – Miranda Loyalty Mission

During Miranda’s loyalty mission, you”ll enter and fight in what is essentially a warehouse. An elevator takes you down to this area, so don’t take a second elevator until you’ve found the upgrade.

After being attacked by Loki Mechs (and then a group of mercenaries, further down the hall) your squad can head across a conveyor belt. On the other side, there will be an office room with a hackable computer and a dead merc who can be searched to discover the medi-gel upgrade.

+1 Medi-Gel Capacity – Normandy: Serrice Ice Brandy

In Mass Effect 2, Shepard is given this assignment to find a bottle of Serrice Ice Brandy for Dr. Chakwas. When they retrieve it, the good doctor will ask to have a drink with you. You are given the opportunity to decline – but don’t. Not only is it fun to get drunk with your usually-uptight friend, but you can also only earn this upgrade after having the drink together. It’ll be rewarded automatically after the cutscene.

+1 Medi-Gel Capacity – Arrival

The Arrival assignment asks you to go rescue Dr. Amanda Kenson from the Batarians who have kidnapped her. While sneaking into the base, you’ll reach a point where you need to activate crane controls in order to progress and clear a path. However, you should actually use the crane controls to lift up the nearby container. If you then go down to where it was, you”ll find the medi-gel upgrade that was hidden behind it.

+1 Medi-Gel Capacity – Citadel: Sirta Foundation

One of the upgrades to your medi-gel capacity is purchased on the Citadel, in a store called the Sirta Foundation. It’s found in the Zakera Ward, in the Mid-Wards District.

+1 Medi-Gel Capacity – Illium: Serrice Technology

The final medi-gel upgrade is purchased from a store on Illium. It’s called Serrice Technology and is being attended by an Asari named Hermia.

Trauma Module

This upgrade, the Trauma Module, is unlocked for you automatically once you have invested in two of the other upgrades.

Emergency Shielding

The Emergency Shielding upgrade can only be acquired by investing in medi-gel capacity upgrades three times.

How To Get Omni-Tool Upgrades In Mass Effect 2

+10% Tech Power Damage – Garrus Recruitment Mission

An explosion interrupts you when speaking with Garrus during his recruitment mission. At this point, you’re attacked by Blood Pack members, and Garrus tells you to head to the basement. Before you do, find the omni-tool on the ground that will give you this tech damage upgrade.

+10%  Tech Power Damage – Kasumi Loyalty Mission

One of the omni-tool damage upgrades is found during Kasumi’s Loyalty mission, as you’re on your way out but before you reach the landing platform outside. After activating the mass accelerator weapon in order to explode the tanks, keep moving and take out enemies as you go.

You’ll drop into a room where you must fight Eclipse Troopers, an Eclipse Heavy, a YMIR Mech – and then a truck pulls up with even more opponents. Take them all out and head for the door but pause – because you find the damage upgrade on the left side of the door by searching a dead mercenary.

+10% Tech Power Damage – Collector Ship Mission

This tech-power damage upgrade is found during your adventure on the Collector ship. As you attempt to escape back onto the Normandy, you’ll have to take down a Praetorian.

The hallway she guides Shepard down has some Collector Technology to salvage and, across from it, there’s a control terminal where you will find your omni-tool upgrade.

+10% Tech Power Damage – Tali Loyalty Mission

Tali’s loyalty mission has Shepard attempting to convince the Quarians that Tali is not guilty of treason. If you are successful and Tali is found not guilty, Admiral Raan will give you this upgrade for your omni-tool.

Thankfully, this power upgrade is an easy one to acquire. You only need to find the Saronis Applications store on the Citadel; it’s located on the Zakera Ward, in the Mid-Wards District.

Quite early on in the Collector Ship mission, you are prompted with an advanced weapon training menu.

+10% Damage Protection – Lair of the Shadow Broker Mission

During the first part of the Lair of the Shadow Broker mission with Liara, you’ll be facing off against Vasir, a spectre.

Before following the trail, access the panel inside the car to get this upgrade.

+10% Damage Protection – Illium: Gateway Personal Defense

To unlock one of the damage protection upgrades, you’ll need to purchase it on Illium. The store you’re looking for is called Gateway Personal Defense, a weapons depot.

+10% Health – Overlord: Atlas Station

This mission, part of the Overlord DLC, has an upgrade available towards the very beginning. You will do a little fighting and then enter an elevator – which proceeds to crash into the bottom of the shaft. The room that you exit into will have a damaged Geth corpse that you can scan for the heavy skin weave upgrade.

+10% Health – Arrival

This cybernetics upgrade is found late in the Arrival mission. Dr. Kenson – the person you were supposed to save but who has clearly become indoctrinated by the Reapers – eventually blows herself up and you are knocked unconscious.

When you awake, you try to contact the Normandy but can’t, so you must rely on the VI’s directions to the escape shuttles. Leave this core room and head down the hall till you reach a door on the left to a dead-end room. This is where you’ll find the heavy skin weave upgrade that provides +10% health.

+10% Health – Illium: Gateway Personal Defense

Several consoles will display messages from certain doctors. Hack the research terminal here to get the upgrade.

+10% Biotic Damage – Project Firewalker: Prothean Site

This quest has you and your squad journeying through a Prothean dig site after taking down its barrier. Inside, you’ll find a lot of things to read and loot.
