I saw this as a 'free giveaway' from freesteamkeys.com or more accurately https://www.freesteamkeys.com/free-dungeons-of-the-dead-steam-level-3-required/ which led to here https://giveaway.su/giveaway/view/851 . It then led to the Steam Store page to a game posted today, April 12, 2018, where I saw something disgusting in the game development world and fully Copyright Infringement: http://store.steampowered.com/app/828230/Dungeons_of_the_dead/ .
Here's the thing, I have seen this before. Where have I seen it before? Never at the Steam Store, but instead on the Unity Website and Unity Youtube Channel. It is from the 2D Roguelike Tutorial posted there on February 8, 2015.
Here is the Unity Page link: https://unity3d.com/learn/tutorials/s/2d-roguelike-tutorial
and the Unity Youtube Page Link: https://www.youtube.com/watch?v=Fdcnt2-Jf4w
This should have never happened. Since I am not the copyright holder, I just sent in a report. Please do this as well, since this does not belong to that developer and they outright stole it. Unity should be contacted as well. This is a huge deal in the game industry and bad practice. Makes you wonder about that company's other games and if they are really their own or if they ripped them off too.
April 18 Update: Got in touch with Unity; they are working on getting it removed! Yay!
