You Are Reading :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!

Updated December 14, 2021, by Gabrielle Huston: Mass Effect: Legendary Edition, a remaster of the original trilogy, has encouraged many players to return to or try out this sci-fi RPG trilogy. Even players who have never controlled Commander Shepard before have often heard of the dreaded “Suicide Mission,” the deadly finale to Mass Effect 2 – and they likely know how important upgrades are to your performance. Not to worry; we have everything detailed clearly for you in this guide.

Locations Of Normandy Upgrades In Mass Effect 2

Types of Upgrades:

• Med-Bay Upgrade
• Thanix Cannon Upgrade
• Advanced Mineral Scanner Upgrade
• Heavy Ship Armour Upgrade
• Multicore Shielding Upgrade
• Modular Probe Bay Upgrade
• Extended Fuel Cells Upgrade

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 Upgrade – 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 upgrade 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 Upgrade – Miranda

Sick of meticulously scanning planets for resources? After Mordin joins the Normandy crew, Miranda will suggest an upgraded 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 Upgrade – Jacob

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

Multicore Shielding Upgrade – Tali

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

Modular Probe Bay Upgrade – Thane

After Mordin gets on the ship, you can also speak to Thane and he will recommend adding an upgraded 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 Upgrade – Samara/Morinth

Speaking to Samara (or Morinth) will prompt her to suggest bigger, upgraded 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.

Locations Of Squad Member Upgrades In Mass Effect 2

Types of Upgrades:

• Geth Shield Upgrade (x 2)
• Krogan Vitality Upgrade (x 2)
• +20% Mordin Tech Damage Upgrade
• +20% Jack Biotic Damage Upgrade

Geth Shield Upgrade – Tali Loyalty Mission

This Geth Shield upgrade is located 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 med-bay. The other is a small office. In the office, you’ll need to hack the monitor to earn this upgrade.

Geth Shield Upgrade – 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 Upgrade – 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.

Krogan Vitality Upgrade – Grunt Recruitment Mission

During Grunt’s recruitment mission, you can locate 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.

+20% Mordin Tech Damage Upgrade – 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 Upgrade – 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.

+1 Medi-Gel Capacity Upgrade – Mordin Recruitment Mission

This Medi-Gel upgrade is pretty easy to locate. 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 Upgrade – 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 Upgrade – Normandy: Serrice Ice Brandy

In Mass Effect 2, Shepard is given this assignment to locate 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 Upgrade – 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 Upgrade – 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.

+10% Tech Power Damage Upgrade – 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 locate the damage upgrade on the left side of the door by searching a dead mercenary.

+10% Tech Power Damage Upgrade – Collector Ship Mission

This tech-power damage upgrade is discovered during your adventure on the Collector ship. As you attempt to escape back onto the Normandy, you’ll have to take down a Praetorian. Then, when you attempt to leave, the door slams shut and EDI calculates an alternate route out. 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 Upgrade – 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.

+10% Damage Protection Upgrade – Collector Ship Mision

Quite early on in the Collector Ship mission, you are prompted with an advanced weapon training menu. Just after this, Shepard and the squad enter a room full of Collector pods and make a few comments. There are some ramps to climb up but stay towards the right.

+10% Damage Protection Upgrade – 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.

+10% Health Upgrade – Reaper IFF

This story mission asks you to find a Reaper IFF device. When you enter the reaper, you’ll find a few logs with messages from Cerberus scientists.

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.

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.

While you’re trying to reach Thane and recruit him, you need to fight your way up a building called Danius Tower Two. Eventually, you reach the roof and fight a few Vanguards and Commandos.
