Now we will start off with Arcade mode and choose any of the 3 planes. They don't differ in more than their looks and their starting sequences, but each of them grants you an achievement so keep track. I started with the leftmost and worked my way across.
Upon starting we will strafe to the left and then quickly to the right. If done correctly you will unlock your very first achievement. Don't worry if you don't, I did a roll accidentally while strafing from side to side.

Now you can see to your lower left a flashing meter. This is your Climax Gauge! As soon as its full it will flash in rainbow colours and as soon as you release your first salvo, another achievement will unlock.

Continue through the campaign and you will come to a level where there is a plane that has a target indicator (red mark) on it. As soon as you shoot it down you unlock another achievement for an emergency order. Go for those each time you see one, as it will unlock an EX option you will need later!

Now play through the Arcade mode until you hit the end and you will unlock the achievements for clearing stage 5 and 10. However, I died a few times and had to continue from the game over screen (which unlocked the EX option for more continues!!), so that might happen to you guys as well since reaching the end isn't as easy as it sounds. However, it shouldnt take more than 3-7 attempts and will grant you the following achievements upon completion.

Cleared Stage 10 in Arcade mode.
Since we reached the end we will unlock the achievement for doing it with the corresponding plane. Since it's totally up to you which one you use, I will state all the achievements here. Be aware that you have to play through it all at least 3 times.

You should've unlocked a few EX options by now and for the following achievements, certain EX options will make them a walk in the park.
For the 50 combo, the best EX options you can have are those for Climax Mode, MG (mostly power ups), larger cross-hair, automatic lock on, infinite rockets and larger combo time. No smoke/explosion effects might help as well, but won't change a lot in my opinion. I got it upon playing normally and using a lot of Climax Mode without any EX options, so its really easy.
Got a combo of 50 in Arcade mode.
For the AAA ranking, use as many EX options as you can. They are all helpful, but the by far most helpful is the speed increase since this will almost certainly give you a AAA on the time option for your ranking. This is really easy and straight forward.

For ending A, there are 2 ways you can get this. The first and hardest way is to get ALL the bonus missions/emergency orders. Simply destroy all the enemies marked with "target" and listen carefully to the radio chatter since they will tell you what to do as well. However, there is a much easier way to do this and I strongly recommend this one. Go to EX mode and activate 'All Secret Missions "ON"' (unlocked upon completing 20 emergency orders). Now simply play through and destroy the missiles (you can't lock on to them) and you get ending A, easy as that. Use every EX option you can use, makes it even easier.

This is the very last achievement and its also a really fast and easy one. Use every EX option you want and simply play through the missions. You have infinite continues nonetheless, so simply finish it all. Upon reaching the leader boards use the option to submit data and the achievement will unlock, easy as that.
Uploaded a Score Attack score to rankings.
Congrats, you now completed the game with a full gamerscore!
