For those stuck on world saviors- I recommend trying to kill their healer, and do it fast. If you can't do it you could try sending them to sleep first. If you don't have legion or can't put them to sleep... then you should get legion and the inventor. The inventor can spray them all to sleep. Don't melee Bernard or melee if you have the song playing that shares damage... or you may get more than you bargined for. I suggest you make sure legion picks up Bernards air spell as only the griffin and hard bosses use it other than him. Bring pheonix dawns.
To say the least, I've spent a while making sure I've got everything I can (expect for a stupid mercenary who you can't reach once the zombies moved) as good as I can from the previous games. 13 hours 46 minutes, and just starting chapter 3.
Is there a non-boss killing way off the spaceship? I acidentally overrided my save game when I got on... and I have rubish items. I don't care if I have to start the entire ship again, but now I have lost my entire game progress because I can't get off.
