(Good idea, that way you'll be able to change whatever it is you want changed and such, glad to see you're deciding on returning. Welcome back!
That's along the lines of what I was thinking too, these zombies could be more advanced and such, making survival slightly harder but allowing us to have more to work with. I had another idea, although it's more like an 'Apocalypse Test' type of thing; they've been left abandoned in a city, similar to the Maze Runner/Hunger Games;
- A small selection of people have been thrown on to this abandoned 'island' which has different locations, although they can't be seen unless the observers want them too. They could have put them on this island which has many different locations and problems, the main objective though would be to see how long they survive with zombies and mutated creatures. A group of scientists or the government? Could be watching them in a secret lab. Now and then new people, animals and mutants/creatures will be placed on said island. With time they could be forced out of the forest to new locations and such with different creatures and problems- although these creatures will be linked to zombies and wherever they go will have an apocalyptic feeling. They could even add groups of living people, whom are more like rebels and want to kill/stop the test subject type things.
I'm not sure what ye think, or if this is seen as too 'unrealistic' but watching a few movies today I kind of got a crazy idea in my head of World War Z, The Maze Runner and the Hunger Games combined. My imagination runs at times.)
