Achievement list

Some sound fun to do like Stealth Master or Master of Drones but it looks like mostly standard stuff. The last few are a little vague and there seems to be a lot of secret achievements for what I imagine would be for story progression. I hope there are a few hidden secrets like the Keeper of Secrets one in The Darkness.
