Many gamers hate DRMs as an unneeded cumbersome burden on gamers that legitimately purchase software. However, Croteam, the makers of the Serious Sam franchise, have managed to protect those gamers and make the life of pirates who don't buy the game miserable.
According to a post at Dark Side of Gaming, pirates that violate the DRM will find their characters in game being shadowed by a huge red scorpion that just won't die. It will follow the player until he is dead and keep doing it as long as the game is pirated.
While the implementation is nothing short of brilliant, I wonder how many will be tempted to pirate the game just to see this armored monstrosity in action?
