Introduction:
Bastion is a critically acclaimed Action RPG from Supergiant Games. This port is done extremely well, and contains some extra DLC that was not available for the Xbox 360 version. You play as The Kid, a non-speaking character who has his story narrated by someone called The Stranger (dude has an amazing voice). You will learn the tragic story of this beautiful world, as it literally builds itself around you on your adventure. Truly one of the best games I've ever played.
Step 1: Normal Playthrough + First Ending:
Your first playthrough should focus on enjoying this beautiful game. You can't do the majority of the achievements until the second playthrough, and everything will reset when you start Score Attack Mode anyway, so there's no use getting partial progress toward anything here. You'll get a minimum of five story-related achievements, and be sure to remember which ending you choose so you can make the opposite choice in the next step.
Step 2: Score Attack Mode + Second Ending
After beating the game once, you'll unlock New Game Plus and Score Attack Mode. Start a second run of the game on Score Attack Mode and it will count for both achievements. Your goal will now be collecting everything possible, completing all the Vigils, upgrading all the weapons, and completing the arena battles with all ten idols active, as well as getting one million total points toward score attack.
Complete the story up until the "point of no return" (the game will tell you that you won't be able to return when you try to select the last level), and then mop up everything you need to do. You should only have one ending achievement left when you decide to move the story to its conclusion on this playthrough. Make sure you select the opposite choice from your first run.
I would suggest playing the story levels with a few idols active this time around. You will get bonus experience for doing so, and this will definitely help toward getting Level 7-8 (or higher) for the arena battles. I personally played with Lemaign, Pyth, and Olak active for a 25% bonus.
