Project Warlock & GOG Contest: win game’s bundles and BIG BOX releases signed by John Romero

No demons will stop the Lone Warlock this Halloween! Or will they?
The spookiest day of the spookiest month is almost upon us. Because of that, we’ve joined forces with Project Warlock to deliver you an awesome contest in addition to the game’s special bundle deal on GOG.
If you’d like to win 1 of 10 keys for Project Warlock I + II Bundle and 1 of 3 BIG BOX Releases of Project Warlock containing stickers, poster, goodie bag, steel pins, custom buckshot USB and of course BIG BOX itself, all signed by legendary John Romero and game’s showrunner Jakub Cisło, all you have to do is answer us one question:
What kind of demon would you create to stop the Lone Warlock from saving the earth?
You can give us your answers by November 2nd, 11 PM UTC on GOG Forum or under appropriate Facebook and Twitter posts. All the details and contest rules can be found HERE.
Show us what twisted monsters are hidden in your imagination!
