Minion Masters, what the freaking hell is it? Sadly, I have no freaking idea as well but the game is currently free in Steam.
If you have a STEAM account then all you have to do is search for Minion Masters, go to its STEAM page and click on the Play or Install Game button.
Doing so will download and install the game and, after that, you can either play it to unlock all the achievements or un-install it to free some hard drive space.
Whatever you decide to do with it after getting it is all up to you. Regardless of what you do with it, Minion Masters is free until April 6 only.
Anyway, if you have any comments, questions or reactions then just post them in the comments section below.
