Step one - Preparation
First off you are going to want to hit , go to 'HELP & OPTIONS'.
Once there go to Settings, at the bottom and set the difficulty to 1. This is the easiest setting.
Step Two - Arcade Mode
The following achievements will be unlocked in this playthrough:
Across Enemy Lines
Strike Eagle/Super Tomcat/Super Hornet
All Clear! (Possibly)
Now you have the difficulty set to your advantage, go ahead and start Arcade Mode. Chose your plane and get ready for one of the best XBLA games to date. As soon as the game starts, press and hold either left or right, this will get you the ROLL achievement. Immediately after the roll, press to enter Climax mode, unlocking the Climax Mode achievement. From here just keep playing through.
I advise that you do not stay still for more than 1-2 seconds as the enemy rockets will take you out. Push the stick and hold either left or right to do a roll to avoid enemy missiles. When you see large groups of enemies, or multiple missiles fired at you at once, you may want to use the Climax Mode to destroy/avoid them.
On certain stages, you are ordered to take out a target. The first target you encounter is Stage 3. This target takes 3-4 rockets to destroy, unlocking the Emergency Order achievement. Upon completion of Stage 5 you will unlock the Stealth Bomber achievement. Also upon the completion of Stage 10, you will unlock the Across Enemy Lines achievement. Once you complete Stage 13a/b, you will have completed the playthrough and gain the achievement related to the plane you chose at the start.
In this playthrough you will unlock the following achievements:
Strike Eagle/Super Tomcat/Super Hornet
Triple A (Possibly)All Clear! (Possibly)Throughout your last playthrough, you may have noticed the Ex Options Unlocked banner pop up on your screen. To activate these, go to Ex Options from the main menu. You will definitely have unlocked extra credits and also Lock-On: LARGE CURSOR. Also activate the Aircraft Speed: FAST. This will help you to get the AAA ranking later on. Click on any of the images to activate them.
Now start your second playthrough, as you now have a fair idea off what the stages are like. As you have to play the game three times, we will leave the tougher achievements till last. This is because you unlock more things in the Ex Options that help you.
Here, all you are focusing on is getting a 50x combo. I found this easier to do on Stage 5. Once you hit the 50x mark, the 50 Combo achievement will unlock. If you can not get this, then just try get a combo of 1000 points. This will unlock a Ex Option (Combo Window: LONG) that makes the combo last longer. This makes getting a 50x combo a piece of cake.
Upon completion of all stages, you will receive the achievement related to the plane you chose.
If you do not yet have the 50 Combo or Triple A achievements, this is the time to do them. You will also receive the last place specific achievement you need.
For this playthrough, make sure you have ALL Ex Options that you know are going to work in your advantage, don't get too excited when you see you have unlocked a few, READ them before activating. Some decrease your plane's abilities.
Try and use Climax Mode as much as you can, this really helps when taking out enemies to try and keep your combo. The easiest stage to get this in my opinion is Stage 5.
As for Triple A rankings, just hold down the whole way through the game, do not let go. This will ensure a fast playthrough getting you the Triple A ranking for time, unlocking the Triple A achievement.
Final Arcade Playthrough
Here you will unlock the final Arcade achievement, All Clear! To obtain this, you need complete all emergency orders given through out the stages, I believe there are four. Once you have taken out the last one, you will unlock the last stage. Make sure you take out the rockets labeled with Target. If you do not destroy them, you get ending B not A.
An alternate way to unlock the last stage to get the ending A is to play 20 Emergency Orders through out the stages. This unlocks a Ex Option that enables you to have the secret stage at the end of every playthrough.
Score Attack Mode
In score attack mode, you need to upload a score for the final achievement. To do this, simply play through the level and have the scores uploaded to XBL.
Thanks for reading and I hope this helps everyone out a little.
