This article has been verified for the current version (1.06) of the game.
Empire of Sin has 51 different achievements, all using the Steam achievements mechanics. Achievements have no in-game effects; the achievement just pops up in-game and then added to the player's Steam profile. It is possible to see the achievements sorted by the percentage of users that managed to complete each achievement by going to the game's global achievements at Steam (for more accurate numbers one can use the Steam web API).
The difficulty of each achievement varies; some achievements are very easy (e.g. Bullseye), while some are more difficult (e.g. Overachiever). The below list groups the various achievements by a difficulty level as assessed by the wiki editors (uncategorized - UC - achievements haven't been assessed yet).
The "Notes" column lists helpful short tips/strategies.
The column denotes achievements which can't be completed without the use of DLC mechanics (currently 4 out of 51).
The "Ver" column indicates in which version a certain achievement was added. Achievements cannot be earned prior to the version they were added in.
The "DI" column is for difficulty as assessed by wiki editors. VE = Very Easy, E = Easy, M = Medium, H = Hard, VH = Very Hard, I = Insane, UC = Uncategorized.
