First Meeting with Cerberus Troops
These troops are fairly easy to attack. Don't shoot them first, charge the guy in the middle of the group to take advantage of the area damage of charge and nova. If you have followed my tips on setting up your character, charge should be ready immediately after you have finished the nova animation.
Nova is the main way you deal damage. I usually charge anyone in the group and then direct my nova towards the middle of the group I am attacking. This ensures that you stagger as many enemies as possible, stopping them from shooting you. Be sure to use overload of your teammates whenever it is ready because it causes a biotic explosion which also causes area damage.
Loading Bay Fight
be sure to level Liara T'Sori's powers up before you start this engagement. She will have around 30 skill points to spend, depending on the level of your imported character.
The best way to get the assault troopers out of their annoying cover is to use Liara T'Sonie's singularity. It took me quite a while to figure that out, and the intention of this part is to get you to use it. Before I realized I felt as though the assault troopers took much more of a beating than they should have.
After the fight look around the bay for a controls that let you raise a platform. They are called "Vehicle Lift Controls". To the left of that platform are a few boxes that you can climb up and then use the platform to jump across to the top walkway.
Once you have walked though a door there is a minor fight with some assault troopers that shouldn't pose any difficulties.
The Room with the Security Controls
This room has some interesting objects in it:
Data pad that rewards you with 75 experience for reading it
1 Med Kit
1 armor upgrade (Ariake Technologies Gauntlets)
A new pistol (M-4 Shuriken)
Long Hallway
After this room you get into a long corridor in which you find a fair few enemies. They are very nicely spaced out so they shouldn't pose any difficulty. Be sure to kill all the enemies before the guardians because they are a pain to kill. Charge into them and once they stagger shoot them in the head. After the slow motion ends and they aren't dead your charge is ready again and you can repeat the process.
Turret Room
Eventually you get to a large room that has a turret in it. The instructions that you are given are fairly straight forward. I found that if I pushed anything but w whilst pushing space Shepard does an annoying barrel roll that got me killed a few times. Once you are out of reach of the turret you can move around freely, even back into the area that the turret could shoot you in before. There are a few enemies in the control room, including a centurion. Be sure to use overload on the centurion whilst charging at him.
After you have killed everyone you trick the Cerberus troopers into sending a shuttle back towards you. There are a few assault troopers, centurions and guardians in the shuttle, but if you charge in immediatly after the doors open and then run towards the shuttle controls and start the shuttle they disappear as you enter the cut scene.
Once your shuttle has broken down and the other shuttle with the assault troopers comes towards you, when it stops you can charge into that shuttle. I had great fun hitting them out of the open door onto the surface of Mars.
Shuttle Bay
This room is full of enemies. It is the final major fight of the mission. Be sure to charge central enemies and place the nova towards the largest group of enemies. Remember to leave the Guardians to last and the charge and shoot them in the head over and over until they are dead. Also use overload as much as possible, even on enemies without a shield as it causes a biotic explosion when combined with charge as well as staggering them and nearby enemies.
Final Room
This last part is mostly story. When you talk to cerberus be sure to use the left conversation options "You're wasting time!" when it pops up and subsequently the red or blue option, red for renegade and blue for paragon. This gives you an extra 5 renegade/paragon points.
Chasing and Killing Dr. Eva
In the chase you can't charge Dr. Eva. However, you can fall behind and fail. I had no trouble keeping up, just be mindful of cover which can sometimes get you stuck.
When Dr. Eva runs towards you shoot her in the head until she goes down. You don't have to take down all her health.
