Mass Effect™ Legendary Edition - Complete Achievements Guide - Walkthrough - ME2 : Missable achievements - 553E304 No One Left Behind

ME2: Keep your team alive through the suicide mission

Sounds hard, but actually really easy, first, you need to have all your crew loyal BEFORE going for the “”Acquire Reaper IFF”” mission.

After the mission, go speak with Legion and immediatly go for Legion loyalty mission. By doing this you avoid the death of the cerberus crew. After that you will be ready for the omega 4 relay

For the collector base, use this :

Mass Effect™ Legendary Edition - Complete Achievements Guide - Walkthrough - ME2 : Missable achievements - E3BBB77

For the Endgame, every teammate equal a number of points, and you need an average of 2 to avoid casualties

Jack/Kasumi/Tali/Mordin are the weakest members, to avoid death :

—– Put Jack as the escort for the crew/DrChakwas (Or any other weak member)

—– Bring Mordin/Tali with you for the final fight (Or any other weak member)

Doing this will make your team strong with an average of 2,55 = Everyone survives

Mass Effect™ Legendary Edition - Complete Achievements Guide - Walkthrough - ME2 : Missable achievements - B4FD4DE Insanity II

Complete two games in Mass Effect Legendary Edition on Insanity without changing difficulty

One of the hardest achievement to do, ME2 is the hardest game in the trilogy to do in insanity. I advice you to play as a

  • — Engineer – For the power “Tech Armor”, which allow you to instantatly have full shield again
  • — Infiltrator – For the power “Tactical Cloak” which allow you to move/retreat/have you shield back. Also, after getting Grunt loyalty, go to the laboratory, advanced trainning and take “Fortification”, which allow you to instantatly have full shield again

Another important thing to know about ME2 is that enemy spawn by waves, sometime rushing is a good way to avoid a difficult room

Exemple here :

  • — 00:00 – Normal way – Waves of Krogans, lasted for 6 minutes, out of ammo (10 Krogans spawned)
  • — 01:05 – Rushing – Use AI as bait, run to the end of the room, use your defensive power when shield are down (fortification used in the video) then kill the last enemies (Only 2 Krogans spawned)
  • — 02:02 – Normal way – Waves of Vorchas/Krogans, lasted for 5 minutes
  • — 02:52 – Rushing – No Krogan or other pyros spawned
  • — 03:46 – Rushing objective – Enemy disappear when objective is completed
