Tom Clancy's H.A.W.X.

You must complete every single chapter in the campaign (18 chapters) on the hardest difficulty available, "Elite" in order to earn this trophy. There are in total 20 other trophies that are directly linked to this trophy. You will earn the 18 trophies for completing each of the 18 chapters. The other 2 trophies are obtained for completing the campaign on "Normal", and "Hard", both of which you will automatically earn once you complete the campaign on "Elite".

Now, you don't need to be alarmed as Elite is not as hard as it sounds. There are however a few differences between "Elite" and the lower difficulties. In this case, you will be given much less ammo than you normally would, lower health and the enemies will obviously be much more skilled. None of the chapters are too challenging except for one chapter which I found difficult, Chapter 14.

You should consider doing this in co-op mode so it's easier. Other then that one chapter nothing is too time-consuming or stressful. By doing so you will also earn the "Team Player" trophy. There are 2 ways you can go about completing the campaign, Solo or co-op.

Solo Play

If you want to go through the campaign solo as you're feeling the need to challenge yourself, then go right ahead, but be warned, it'll take a lot longer and will be more difficult then when you are player in co-op mode. A few things you should always remember.

- DO NOT use assistance off mode as you will get massacred if you do so. The reason being that it is much harder to aim and you basically have to fly on instinct. and trust me, that is not the way you would want to fly when playing on "Elite".

- Multi AA missiles are your friends, use them in every level that has a large number of enemies as you can kill up to 4 enemies at a time.

- Radar Guided Missiles should be used whenever you need to kill enemies/armed turrets on the ground, but only when they have a large reticle (large yellow ring) around them indicating the range at which the turret can spot you. This will reduce the risk of you being shot down.

- Joint Strike Missiles should always be large in number in which ever plane you decide to choose as these are very necessary when playing chapters with many enemies.

Co-op Mode

- Naturally, this will be much easier as you can have a maximum of 3 other people helping you. It will basically be a piece of cake unless you have very unskilled partners. Again, keep all the tips I mentioned in the "Solo Play" section of this trophy in mind.
