I don't know whether I will have time to do an actual entry, but I'm playing around with a few ideas, and I just wanted to share the concept of one of them.
However, if you have an idea that cleverly interprets the theme without being one of these specific entities, it is certainly allowed (providing you make it clear as to how it fits the theme).
I particularly found the idea of 'interpreting' the theme interesting; according to wiki Undead is a collective name for fictional or legendary beings that are deceased yet behave as if alive
. So what could be an unexpected (but fitting) twist on the theme? - Well, there's this one guy who died and came back to walk the Earth (and no, he didn't start Christianity about two-thousand years ago):...Boddicker executed Murphy with a gunshot to the head. Murphy was transported to the hospital emergency room where he died and his remains were used by OCP in the construction of RoboCop.
. He's deceased yet behaves as if alive. And that makes RoboCop undead.
I don't know if I have time to finish anything, and even if I will I don't know if it's going to be RoboCop, but I just wanted to share this and hopefully motivate people to look beyond the obvious.
Nice theme Ben
