Nevertheless they do not have a server check for quest completion. That means you are able to buy heroes that requires you to complete certain quest without having to complete them. (if there is a level/neighbor requirement then you have to fulfill those first.)
This also means some quests can be auto-complete (unless they happen to be quest that require certain area to be finished or population check.) Oddly, some quests that require a money/item check can be bypass...So that means about 65% of the quest can be completed without having the requirement.
Anyway, tools and instruction you will need for some editing:
Charles
Textpad/JSON editor (or any txt editing software that does not have a line limiter)
Some time
1. Open Charles
2. Start up HC
3. Look for

4. Expand and find data folder, expand that as well
5. Right click on 7045.json and save respond
6. Open up the 7045.json that you saved with a txt/json editor, edit, and then save it
7. Go back to Charles, right click on 7045.json and map local
8. Browse to your edited json file and click ok
9. Log out of facebook, clear cache, and reload.
This last step can be avoided if your game crashes due to "browser has been enhanced error" and you are forces to reload the json file. Hence you can save time if you edit the file in a way to crashes when you buy a hero (that require # of neighbor for example) and just f5 to reload your browser.
I also attached my own edited json files that have quest from 20-40 that are completable already completed. Just have to do the prerequisite quest before so it pop up and you can just claim the reward. Also certain heroes are edited to be buyable without doing quest (javatara, snowman etc...). and limited heroes has been re-enable so those with cash can buy them (spartan, ghost rider, sailormoon, etc...)
Lastly, all the server checks are done in the 7044.swf file that is located under
-> Hero City -> 7044.swf. The problem is the swf is compiled with a flex builder and I cannot recompile it back after editing from the decompiled file with Trillix. I also attached the swf for those who can edit it, if they want to, to do so.Have fun.
Virus scan for json file:

Forgot to mention that I also enable the halloween and zombie event area with the attached json file.
