Dishonored

Recommended knife of Dunwall dlc
Their is a maximum of 7,705 coins to collect over the 4 missions plus the 3,000 you collect from starting the dlc which doesn't give you much room for missing out on coins.

But if you have the Knife of Dunwall dlc you can start this dlc with more coins than you usually start off with for this achievement I would recommend getting around about 5,000 coins and in each level try to aim for amount of coins that are listed below which are not that hard to collect.

Mission 1: Choosing your mark: 500/500, coins shouldn't be too hard if you use void gaze level 2.

Mission 2: A stay of execution for Lizzy: 1300/1655, use pull to grab coins off of the belts of guards and off of tables with some exploration you could find more than that just to be certain.

Mission 3: The dead eels: 2200/3520, there are a lot of coins missing in this level but you could easily find this amount of coins without trying. By now you should have around about 9000 coins.

Mission 4: Delilahs Masterwork: 1020/2030 same again just be careful getting into the mansion but after you hit 10,000 you will probably want to finish the mission. Not sure on if you will get the achievement by having exactly 10,000 but I had 10,057 coins when I had finished. Make sure that you have 10,000 coins before entering the Void as their is no coins there. At the start of the mission purchase the favour theiving butler which costs 75 coins but at the start of the mission turn around and jump In the water their will be a chest with 150 coins so its worth it.Credit goes to MisTaKez AE for discovering how to spend coins to receive more coins in this method for sneaking in more coins.

Bonus coins:
In the missions the dead eels and Delilahs masterwork you can find these plants that will spit acid at you by killing these you will earn 50 coins which will contribute to your 10,000 coins. By doing this it might void your cleanest hands achievement. Credit goes to Xela Killaz for discovering this method for extra coins.

When on the Knife of Dunwall dlc you will want to make sure that you have void gaze level 2 Blink level 2 and bend time level 1 save all other runes for the Brigmore Witches as you will need pull level 1. All remaining runes should go to bend time level 2 because if you get pull level 2 you will pull the person instead of the coin pouch or key.

Note: (Thanks to I Ant Tr4ckzZ for informing me and confirming) You can load up a high chaos save as long as you finish the brigmore witches dlc in low chaos will still get you the achievement.

If you leave a negative vote please leave a comment on how to improve and I will edit the solution in order to make it better.

This has a list of all the coins in each level for the Brigmore Witches DLC. I didn't make the guide, credit goes to hinkel. I only had to use the guide on the last mission to find 9 more coins that I couldn't find. So I think this could help if you're short on a few, search almost everywhere, but can't find them.

I found this post on x360a http://www.xbox360achievements.org/forum/showpost.php?p=5948... thanks Verbalibis

Basicly you don't need to be stealh at all and you can kill everyone if you wish so. I just tried this and to my surprise it works. You'll get Enough Coin to Disappear & All Come To Ruin achievements this way

Here is a video guide for the locations of all of the coins in all of the missions and certain strategies to help you get through the missions.

* You start the game fresh with 3000 coins. No matter how much you have when you finish KoD (< or > than 3000) that is exactly what you will start with. If you import KoD and you don't have at least 3000, just do another KoD runthrough again. It's a lot less stress

* You can kill River Crusts and the Hounds in this game. They are not actual living creatures so you can suffer no penalty.

Not a full solution but a tip that can save you lot of trouble and time wasted on carefully hiding from being seen. In mission Dead eels there are two areas where you can turn enemies neutral which will make finding loot way easier. In Waterfront area - where the undine boat is - you just need to quickly blink through the right hand side, jump straight into the water and find a hatch on the bottom side of the ship. Neutralize Edgar Wakefield (choke or sleep dart if you're going for cleanest hands) and blink to the roof of the ship and pull the horn. From that moment you're free to explore and no one will stop you nor you'll be spotted.

Then you need to travel to the Mill. Same as before. Don't bother finding loot just quickly blink to the second floor. If you have blink 2 then using left hand side path through the guard house roof, pipes and though the mill window is the quickest. Speak to the Geezer and promise him you'll turn the water on...

And a final tip: if you're not going for coins you can totally skip this and just go straight to the safe, enter the combination (for me it was 258), steal the damn thing and return to the undine.
