From Before I Play
- follow-up attacks are incredibly useful, and incredibly devastating. Make sure more than one team member at a time is near an enemy when you attack, especially powerful enemies that can counterattack. Likewise, don't get swarmed or you're going to get murdered in a single turn.
- You can't get the 'good' ending in a single playthrough, as you need to max out your affinity with every character to do so.
- Diversify who you play through in each battle. One, because you have no idea who's going to be eliminated before the next area, and two because it helps discover who's the traitor in your group.
- Nothing stopping you from replaying levels over and over again to get experience and make certain who the potential traitors on your team are.
