Yup, an immortal pink scorpion that will chase after you forever! but of course this will only happen if you chose to pirate Serious Sam 3. This is the developers way at getting back at you if you choose to pirate their new game. Some might not like the idea, I think its genius.
Pure genius, I wouldn't mind if this becomes a trend for future game releases to hurt piracy. Of course they will find a fix to work around it but its still a pain regardless. I'm actually curious on pirating it to try it out, but damn that scorpion is fast. Serious Sam 3: BFE is now available in Steam, Playstation 3 and Xbox 360.
