Before you actually land on Mars, you'll have a Paragon and Renegade interrupt opportunity while talking to James.
Level up if you need to (you likely do). When you are done placing ability points, follow the ridge along the right side. You will come to a point where you can drop down and when you do, you'll find the M-92 Mantis Sniper Rifle at your feet.
NOTE:
| Picking up a new weapon will allow you to change your weapon load out. If you change to the new weapon, note that you won't have any mods on it. Remember that your carry weight affects Power recharge speed so if you are a power heavy class, equipping the Sniper Rifle may be more detrimental than helpful. |
Follow the nearby path and you'll come to a Mako-like vehicle with a group of Cerberus. If you have the sniper, take a shot at one of the enemies and then immediately cue up powers for everyone. I would take cover behind the right barrier rather than the left. It seems to provide all around better cover so you aren't attacked as well from the sides. Watch out for grenades. If they throw one at you, go to the far side of your cover and you should see an arrow pointing directly to the other piece of cover. Hit A and you'll roll over to the other cover and be safe.
After they have been cleared out, make your way down to the vehicle. Then start going up the hill on the other side. You will encounter another Cerberus Group here that will be a little bit tougher. There are more of them, they have a height advantage, and the cover isn't close enough for a combat roll. My best advice is to have everyone on your squad focus on one enemy and be extra careful. If they throw a grenade at you, you're going to want your shields as high as possible so that you can run for new cover.
Go up the hill the rest of the way and take a right into the compound. Once inside, you'll meet an old friend and send James back to the ship. After this point, you'll have a sort of tutorial on using Singularity. Use it to pull the troops out so you can shoot them. Kill them all and then head to the left to activate the nearby vehicle lift. Go up the nearby ramp, climb the boxes and jump over to the vehicle. Vault over the railing and then make your way over to the door ahead and to the right.
In the next room, take cover and slide to the right. Use the instant-kill melee attack from here. Any time you melee an enemy from behind cover like this, it will be an instant kill. This isn't particularly important in normal play but fantastic for Multiplayer. Clean up the other enemies but watch out for grenades. Head for the door at the back right of the room.
In the next room, check behind the large reception desk for the Ariake Technologies Gauntlets just as you walk in. On the nearby wall will be a Med Station and some ammo. On the floor between the legs of a dead man will be the M-4 Shuriken. Pick that up and watch the cutscene. From here, head up the stairs in this room and take the door on the right side. This will bring you outside.
NOTE:
| The M-4 Shuriken may not appear if your class began this mission with the weapon |


Outside, turn left and drop down the ladder. Turn left at the corner and head towards the ladder. Just before the ladder on the left will be the Kassa Fabrication Chestplate on metal stack. Go up the ladder now and jump the gap to the right. After you cross the gap, turn left and go into the dark doorway. Take a sharp left once inside and walk into the darkness to find that stairs lead downward. You'll come to a large dark room. There's a large ring around the outside. If you follow it, you'll find a datapad for some XP. From here, head down the stairs to the lower part of the room. You'll turn your lights off automatically. Go up to the far wall at the front and do an instant-kill on one of the enemies on the other side of the glass. Now fight the enemies off from here. These enemies shouldn't pose a problem because they likely won't vault the middle and you're on even ground. Kill them and hop barrier. Go up the small stairs and take the left door.
You'll find yourself in a small, damaged room. There is a work bench just to your right and a datapad by the stairs as well as a mod tucked into the wreckage in the middle of the room. Head up the nearby stairs and go through the door. When you open the door, you'll see some Cerberus in the distance who are unaware of your presence. Take cover just to the left and get ready to surprise them. Hit them with a singularity to start things off and then start blasting away. Because of the tight confines, you may have picked up three or more enemies with that one singularity and prevented the rest from moving on you. Kill the enemies here and then explore the right side of the next room for a datapad.
At the next corner, turn left and you will find more enemies. You may have to back track a little to get good distance on them. Be particularly careful of the Guardians here. Try to put a Singularity just behind them (or use Pull on them if you can) which will pull them back from behind their shield. Clear near the door way and move up to the doorway. Start clearing down the long hallway and gradually move up. Watch out for enemies flanking on the left as you go. Once you get to the end of the hallway, Cerberus will lock you out of a room.
Nearby, you'll find a terminal next to a door that leads into a side room. In the room are two laser walls. If you activate the terminal, the walls will start moving and if you activate the terminal again, they will stop moving. You want to stop their movement when they create a tunnel that leads up the stairs at the back and all the way to the door on the right. Once that is set up, go into the room and collect datapad and med kit from the room. Go through that door and at the intersection, go left. Turn right at the corner and in the distance on the right will be a dead soldier with the M-23 Katana nearby.

NOTE:
| The M-23 Katana may not appear if your class started this mission with the weapon. |
Open the left door and watch out for the turret. You'll have to bounce back and forth up the hall to stay in cover and not be shot. When you get to the end, take cover in the middle and then slowly start making your way along the left. Use combat rolls to get from one piece of cover to another when you can. Eventually you will get behind the range of the gun and a group of Cerberus will come out to confront you. Go through the nearby door and take cover at the corner of the wall as the room turns right.
This room will open into a larger area with many Cerberus and they'll make frequent use of smoke grenades to obscure your vision. Keep hitting them with everything you've got and be opportunistic. Every time that smoke comes down, try to get another kill. If you get rushed or they throw a grenade your way, don't be shy about retreating out of the room and then pushing back up to that corner. The biggest concern here is that you need to be careful with your squad because they seem very drawn to the center of this room where they will die. Make your way to the other side of the room.
After you kill them, go to the room on the other side. Near the glass will be a datapad and a locker just left of it which has a Sniper mod in it. Use the computer to the right to trigger a cutscene where one of your squad members has a great idea.
After the cutscene, place one of your squad members in the blue circle. Once they are there, place your other squad member wherever you would like. Get ready because a group of Cerberus are going to come through the middle of that large doorway below. When they come, they'll be aggressive and try to rush you. Use Singularity on the stairs leading up here from the lower level and they won't be able to get by. Now just shoot the fish in the barrel and board the tram they just used to get here. Part way to the other side, you'll be attacked by more Cerberus troops on another Tram. Singularity can pull them right out of the tram and let them fall to their deaths. Kill any stragglers and board their Tram. This will take you to the far end of the rail.
When you get to the dock, you'll have to fight some more Cerberus troops. I would set my two squad members up at the front of the tram car while you go further back and stand behind a pillar. This should keep you out of range of most grenades, allowing you to relax and pick out targets as well as to watch for any enemies trying to flank you and come in the door. Be careful of any shielded enemies that come at you. Make sure to take their shields so that you can use biotics on them. Once you've cleaned out most of the enemies, move up to the boxes just outside of the car. When all is clear, move to the back of the platform. On the back walls, grab the Shotgun mod on the right and the M-15 Vindicator on the left. Check inside the small ticket station for a med kit and then go through the nearby doors.

| Effect Military Ratings |
| To get the best ending while having an Effective Military Rating in the 4k-4999 range (usually requires 5k+), you must use the Charm options available each time you talk to the Illusive Man. Intimidate will not help you do this. |
When you regain control, you will need to try and catch Dr. Eva. You don't actually have to deal any damage to her so just keep running. Follow her out of the room and she'll go into the center security area (previously med kit). Go in and open the gates, then follow her up a ladder to the left. Once outside, you'll be attacked by some Cerberus in a hovering shuttle. Kill the two men and keep chasing her. At the end of this platform go right and down the small ramp. Follow her through the under areas and at the end she will climb up left and go up a ladder. Follow her up and continue the chase.
When you regain control again this time, shoot her a few times in the head until another cutscene is triggered.
