Tips on how to achieve the above descisions and why?

- With Wrex on Virmire make sure you have been leveling up your charm or intimidate skill to at least 4 levels from max, and also try to have at least 45% Paragon or Renegade points filled in the bars provided around character potrait in the level up menu.

- Always save the Rachni Queen because one way or another there are going to be Rachni husks known as Ravengers in Mass Effect 3. Only difference is the Rachni Queen will want to fight alongside you to help defeat the Reapers. And if you did kill the Rachni Queen in Mass Effect 1, never trust the Rachni Breeder in Mass Effect 3 since it was created by the Reapers.

- Saving the Council grants you more Salarian, Turian, Asari war assets in Mass Effect 3 and also gives you the Destiny Ascension as a powerful war assest.

- If you save the colonists and spare the asari that was being used by the Thorian they will ask for help in Mass Effect 2 on the Planet Illum which you should do since this will cause them to become a war asset in Mass Effect 3.

- For those who get this DLC always let Balak live since not only do you get access to powerful armour in Mass Effect 1, but Balak will reappear in Mass Effect 3 and will give you a strong Batarian Fleet as a valuable war asset.

Mass Effect 2

- On Freedom's Progress never give the Quarian Veetor to Cerberus, instead always let him go with Tali. And when you are at the Floatilla after learning of the ship being taken over by geth, before proceeding to that ship walk around the court room and speak to every character that can be talked to. After saving the ship from the geth you have three options:
1. Rally the Crowd - which would be available since you talk to all talkable characters in the courtroom, this will make Tali not get exiled but not become an Admiral
2. Paragon Choice - This will prevent Tali from getting Exiled but will also make her an Admiral
3. Renegade Choice - This will prevent Tali from getting Exiled but will also make her an Admiral

Save or Destroy the Geth Heretics in Legion's Loyalty mission is totally up to the player if they want more troops or more ships. Since if you save the Geth Heretics the Geth will have more troop forces. And if the Geth Heretics were destroyed the Quarians would have more ships.

If you save the Genophage data the Female Krogan in Mass Effect 3 will live and help Wrex restore peace between the Krogan and prevent the Krogan becoming warring savages again.

If you download the DLC Lost Memories let Kasumi keep the Greybox since not only will it keep Kasumi Loyal in Mass Effect 2 but it will also allow you to get these two war assests instead of only one of them:
1. Spectre Forces
2. Hanar and Drell Forces

Zaeed's Loyalty mission doesn't affect Mass Effect 3 so just leave the refinary workers and let Zaeed kill Vido that way he will be Loyal in Mass Effect 2.

Never side with Morinth unless you really want to fight her in Mass Effect 3 on Earth as a damn Banshee.

Don't choose sides with Miranda or Jack, you need to have about 90% Paragon or Renegade points to select the Paragon or Renegade choice. Doing this will keep both Miranda and Jack Loyal to you

Same thing as above applies to Tali and Legion, but with them if you can make them sort their problem out peacefully it will help you in Mass Effect 3 with uniting the Quarians and the Geth together as Allies.

Most obvious why would you give a base that nearly created a human reaper to the Illusive man who starts working for the Reapers in Mass Effect 3.

Talk to Tali about Normandy Upgrades and she will make the Shields available for you to purchase, You Talk to Jacob about the Normandy Upgrades and he will make the Armour Upgrade available for purchase and you talk to Garrus about Normandy Upgrades and he will make the Weapon Upgrade available for purchase.

Common Sense even Miranda said you need to send a tech expert and Legion and Tali are the only two pure Tech Experts you have in Mass Effect 2

As for the leader of second squad common sense would be Miranda since she is your second in command but you could also send Garrus since he also is extremely experienced in leading a squad since he once had a squad when he was on Omega.

Samara would be recommended since Jack sometimes does glitch even if loyal in this part.

Mordin is a scientist not really a powerful or deadly warrior/assassin. And there has been many glitches where he would die in the part where the rest of your team hold their ground while you fought the Human Reaper.

If you get this DLC it will affect the war assests you recieve from Grimmson Academy along with another war asset on a different mission.

Mass Effect 3

Save the Quarian Admiral who crashed on Rannoch since he wants peace between the Geth and the Quarians, and will help you bring peace between both races.

Same as above and also prevents the loss of Quarian war assets, doesn't affect Geth war assests

If you get this DLC you will learn of the Reapers Origin and get some Reaper forces that are controlled by Leviathan as war assests.

Who in their right mind would betray Wrex seriously

Basically in the description make sure you shoot the Illusive man before he shoots Anderson

If you have Jack alive in Mass Effect 3 you get maximum war assets from Grimmson Academy and Jack as a war assest as well, however put the students on a support role in the war not on the front lines else they get killed and you loose war assests.

Same as explained in the Mass Effect 1 area release the Rachni Queen to gain her as war assests.

Stop Samara from commiting suicide and you gain her as a powerful war assest

If you warn Miranda about Kai Leng she will be able to survive the next part below

You must Renegade or Paragon Miranda's father into letting Oriana go and if you did war miranda about Kia Leng, Miranda will smash her father out the window behind him and will still be alive.
