As you probably already know, Min Hero is a Flash-based game.
Back when it was released, you could mostly play it online on websites like Kongregate, Friv, etc etc. There were (and still are!) ways around this of course, and that is exactly the topic for this page!
This page is dedicated to playing Min Hero offline.
For doing so, you'll need to download a Launcher, and an SWF file (the game itself).
I highly recommend Square_nine's Release for this , but here are some alternatives.
Flash Player (Launcher)
SWF download 1
SWF download 2 (in case the first didnt work)
After you've downloaded these, open the Launcher. Click File > Open... > Browse > pick your SWF file and there you have it! A functioning offline Min Hero :)
