Question for people who have put a bunch of time into this game. I don't want to MISS any achievements. Or screw something up so I will have to restart the entire game. Can someone tell me exactly which/if any achievements can be missed or screwed up?? Here are some that have me concerned.
Personal Vendetta - Kill every Templar. Are there any that you can just miss and not be able to go back for??
Hungerer of Knowledge - What the hell is this achievement??
Conversationalist - Can you screw it up and not be able to get this one??
Disciple of the Creed - Assassinate all targets with a ful DNA bar. So this one really sounds like you can screw it up.
Defeat 100 Opponents without dying - is it possible to kill everyone and therefore not be able to get this one??
Any Secret achievements that you can screw up or miss??
