STAR WARS Battlefront

This is a complete guide to destroying people in Fighter Squadron. Also shows you where to find the Millennium Falcon & Slave so you can fly them. Easiest way to defeat the other is to get in the Falcon or Slave.

This achievement can only be won in the game mode Fighter Squadron. It is awarded for killing the opposite side's heros, i.e. the Rebel Alliance's Millenium Falcon and the Empire's Slave I.
As battles end as soon as one side has collected 200 points, this gives you very limited time to make this work. In addition, it is almost impossible to kill the heros with ordinary fighter craft, unless you team up with various teammates. However, attacking with non-hero fighters makes you vulnerable to attacks from enemy fighters, to whom you act as an easy target with your full attention focused on the hero.

Thus, this solution will focus on fights with you commanding a hero ship yourself.

As soon as you start up the game, fly close to the ground at low speed and circle the area. After a while a hero icon pickup will spawn somewhere in your vicinity (it looks like a circle with a bar in the middle - or a lightsaber with a glowing aura). Note that the spawn points are random, but they are generally somewhere in the middle of the map.

Collect the hero pickup, then press to transform into the Millenium Falcon (if playing as Rebel) or Slave I (if playing as Imperial). Make sure to not fly into anything or get killed while collecting the pickup, as you lose it when dying.

Now continue with the battle until an opponent has also become a hero; you will notice "[Gamertag] has become Millenium Falcon" (respective Slave I) in your battle log. Try to fly high so you get a good view of the battlefield; identify the opposite hero and chase him down. Do not waste time attacking anyone else.

As soon as you are chasing the opposing hero and reach firing range, push back to divert your full energy into your weapons and thus increase damage dealt. You will notice that this slows you down as well, which makes sharp turns easier to accomplish.
Keep firing, but be aware of your weapons overheating; include quick pauses of 1-2 seconds to avoid a longer forced pause while your overheated weapons cool off. Use your torpedoes as soon as they become available ( for the Falcon, both and for Slave I).
Both ships are so strong that you can almost ignore incoming fire from other fighters. As the Falcon, activate your shields when available (with ) to add more protection; as Slave I, try to use the sensor jammer () as much as possible so that other fighters can't get a lock on you.
Feel free to use evasive maneuvers (, , ) to avoid incoming missiles, but use this only rarely to not lose precious attack time.

Keep at it, and eventually you will destroy the hero. In most cases it will be a close call to the end of the match, also depending on the skills of your opponent. Note that the kill will only count towards this achievement if you are the one to give the opponent the final blow. It will show in the battle log as "[Gamertag] has destroyed Slave I/Millenium Falcon"; your achievement counter in the achievement app will also advance to 50% respective 100%.

Update: After the March 2016 update, it is no longer possible to progress with this achievement by simply ramming (and thus destroying) the opposing hero:
"Fighter Squadron: Vehicles of equal size will now both be destroyed when colliding regardless if one vehicle is shielded"

Just to add to the other solutions. If you are struggling to shoot down either the Millennium Falcon or Slave I and ramming them doesn't seem to work for you, this should be the solution to fix that:

Playing as the Slave I you will get the kill on the Millennium Falcon if you ram into him and you both blow up.

However,

Playing as the Millennium Falcon you can get credit for the kill by turning on your shield and ramming the Slave I getting you the points and actually keeping you alive in the process.

Hope this helps clear things up!

The simplest way is to use the hero ship and ram it against the other.

I was trying to do it by shooting it, but either someone would steal my kill or they would kill themselves by hitting the ground. Ramming is much faster and certain.

This achievement can be somewhat tricky, although picking up the hero pickups can make this achievement very easy.

To take down the Slave 1: Get a Millennium Falcon hero pickup, locate the Slave 1, activate your shield (by pressing LB) and crash into the Slave 1. This will get you the kill and often you will stay alive after doing it.

To take down Millennium Falcon: Simply get a Slave 1 hero pickup and crash into the Millennium Falcon providing that the Millenium Falcon does not have it's shields up.
(If the Millennium Falcon has it's shields up, then you will be killed if you crash into it).

This is possible with 4 players. Search for a Fighter Squadron in the non DLC maps. This only needs 4 players to start, you may have randoms join. Easier then trying to get 12 people together for the DLC maps
