The one qualm I have with this game is the buggy nature of Achievements; there are ones I know I've gotten multiple times that have yet to unlock on Game Center (but are unlocked in-game), and there are ones that I haven't unlocked that are said to be unlocked in the game or in Game Center. That said, I'd like to ask how to receive some of the Achievements I've "already received" (but haven't), namely:
- [Secret] sacrifices himself for the greater good.
- I Can't Do It
- I Know a Guy... (George Romero) --- You are the polished pearl grips of your father's .45
