This game is rather basic. You go on short missions, most lasting between 5-10 minutes. There are a few different types but it all leads back to flying around, locking on to things, and pressing buttons. You'll have to play the game 4 times total.
Step 1: Playthrough 1
In this playthrough you are going to focus on getting achievements and not worrying about gold rankings at all. Follow the guide to see what is in store during this playthrough. You should get almost all of the achievements in this playthrough except for a few which will be on the next playthrough. You will want to skip the bonus missions entirely. Now that you have beaten the game once, create new games on each save slot (each different owl on each remaining save slot). You should get the new game+ achievement for this as well. I would suggest highly picking any owl but the Spotted Owl, as it's the weakest of the owls. Even though it's the fastest, you will take much more time killing enemies.
Step 2: 2nd Playthrough, Gold Medals, Bonus Missions
Now that you've played through the game, you'll have a great understanding of the mechanics and how to chain attacks and complete missions faster. Use this knowledge and your Battlesets to finish off all the gold medals in the game on this playthrough. Then, go to the bonus missions and find all of the scrolls and get golds on the seperate missions within. For the scrolls you have help from a changing green to red indicator on your screen telling you if you're close or not. On this playthrough you should be able to get almost every level done with a gold ranking except maybe 2 or 3. If you have a lot more to get, just move on to a third playthrough and afterwards, pick whatever playthrough you had gotten most golds on. Replay the ones you don't have gold rankings on to get them.
Step 3: Last Playthrough/s, Mopping Up
If there's any reason you haven't gotten an achievement, just replay whatever mission you need to get it. Look in the guide for a proved method to obtain what it is you're missing. Now you just have a playthrough or two left. You should be able to soar (literally) through the playthrough in just around 3 hours or less.
This is one of those games you can play for easy achievements. Though there is a good amount of replaying levels which could be somewhat tedious. Other than that, it's a straight forward game with decent flight mechanics and average graphics. The playthrough time depends heavily on how much you replay missions and how long it takes you to find the hidden scrolls. Sometimes you'll find the first 4 scrolls in only 10 minutes, then the last one might take you 45 minutes to find. Hopefully the scroll video will help make this a lot easier. After you have done your last playthrough you will be awarded the last achievement.
