The Ultimate Sacrifice
Complete the Arrival DLC ("Arrival" downloadable content)
This trophy is easy enough, this is your reward for finishing the DLC. The DLC isn't hard at all, and there are no boss fights or difficult decisions to make. You don't have to worry about wrong turns either as it's extremely linear. Difficulty doesn't matter for this trophy so just kick back and enjoy the storyline that ties ME2 into ME3
Survive all five waves in the battle for Object Rho ("Arrival" downloadable content)
This Trophy is Missable!
After escaping the planet with Dr. Kenson, Shepard will learn of the Reaper threat and what Dr Kenson plans to do to stop them. You will finally get to see the proof that she keeps speaking of in all of your conversations as well. When you land on the outpost, follow her and after heading up an elevator you will come to a stop in front of a door. This is where the battle will take place. Head through the door and watch the cutscene, don't worry I won't spoil it for you, then as soon as you have control of Shepard again, head either right or left to the back corner. Now in your bottom right you will see a blue meter that says "Power Level", this is your wave meter. You need to survive until this is all the way filled which is the final wave. Use the small islands for cover, and use your elemental ammo, I think Incendiary Ammo works best in this situation to take out the waves of enemies. Eventually the enemies will get stronger and you will get a couple Captains with shields and near the end of the waves their will be on large Battle Mech to take down. Use Disruptor Ammo on these to take out their shields, then switch back to Incendiary to finish them off. Once you have cleared the final stage, there will be a small energy explosion from Object Rho and you will go unconscious and receive your trophy.
If you die before you have cleared the waves, your screen will turn red, and you will still be able to move until a cutscene starts. This is how you know you have failed. if this happens, IMMEDIATELY exit the game out to the XMB then reload the game and select Resume Game to restart at the Auto Checkpoint which is right outside the doors to Object Rho If you wait until the cutscene ends to exit out, the game will setup another Auto Save and you will have to replay the entire DLC.
Rescue Dr. Amanda Kenson without attracting hostile attention ("Arrival" downloadable content) This Trophy is Missable!
Your very first objective when you land on the planet, is to find Dr. Amanda Kenson. This trophy requires some stealth as you cannot alert the guards to your presence before you find her. From the beginning you will open up the door and proceed into the facility. In the first area, you will come across several lizards. Now I'm not really sure if these are included in this trophy or not. They will attack you with extreme hostility and there is no way around them. The part I'm unsure of is whether you can shoot them or not and still get the trophy. I chose to just run past them and still got the trophy but if someone else tries killing them and gets it, let me know.

Instead, look to the raise platform on the right side if you are facing the guards. Use this to climb up and totally bypass them. Head through that door and drop down from the piping to get access to the stairs and the door out of this area.
Now there will be another set of guards inside the room in front of you. There is a door way behind the room, and on the left side. Hug the outer wall to ensure they don't hear you and turn suddenly and before going down the hall on the left side, peek around the corner and wait for the final guard of this area to head through the doorway at the end of the hall. Once he has, hug the outside wall and head to the end of the walkway, and through the door on the left side. DO NOT GO RIGHT ON THE WALKWAY OR THE GUARDS IN THE ROOM WILL SEE YOU THROUGH THE WINDOW!
In the next room, press the button on the right side of the three buttons to move the crane giving you access to the lower floor. Press the button on the lift on the bottom to lower the crane and you can then climb down its boxes to the very bottom. From this point, follow the path to a control room and press the button on the wall to gain access to the tunnel in front of you. Head down this tunnel and hug the wall on the right. there are two guards in the room on the left watching the interrogation. Head through the 3rd door on the left side going down the hallway. It will be the last open door down the hall, DO NOT GO THROUGH ANY CLOSED DOORS IN THE HALLWAYS OR YOU WILL ALERT THE GUARDS!
In the next hallway head down to the end of the hall to the Interrogation Room through the open door on the left to initiate a cutscene. Once the cutscene has ended the trophy will unlock.
