So, I have a new idea for Shelter: A Post-Zombie Game
I'll try to be compact.
_________________
A zombie epidemic breaks out after an accident at a military lab.
Most cities are evacuated and then nuked with non-radioactive weapons to kill the zombies inside.
Survivors scatter into small settlements, fighting off the zombies on their own.
Years pass. Zombies start eating each other and eventually die off from starvation.
While this was happening, a small percentage of zombified population found themselves recovering from the virus.
They set up "Recovery Camps", where they slowly nursed themselves back to health.
Those camps were eventually raided by "human" survivors.
The Recovered, while clearly lucid and not zombies, were treated with hostility and suspicion. "They did this to us! They could turn at any moment!"
They become labeled as "subhumans" and get tattooed with the word "sub" to distinguish them from the "real humans". Enslaved for their "eternal debt" to humanity, for "what their parents have done". Kept under watch because they "could turn".
Decades pass.
You, the Player, are a descendant of the subs, a sub yourself. A slave. In a small, peaceful settlement.
__________
THE GAME STARTS with you at your Master's house. It quickly becomes obvious that your Master has grown to trust you, but he is under pressure of his peers.
You see, there was a distress signal from a nearby settlement. An attack by REAL zombies, not seen in many, many years. Then the radio went silent.
The settlement is stirred by the news. Tensions rise.
They don't want to send "real humans" to investigate, and you've grown to be trusted. Plus, they have your parents nearby, also slaves, living in a claustrophobic hut next to another Master's house.
So, your first quest is to investigate. If you don't return after a certain time, it is hinted strongly that your parents will meet an untimely end.
When you leave the settlement, you can go investigate, or roam elsewhere, but investigating will be one of the main plot points so it will have to be done at some point to advance the main arc forward.
During your investigation, you see evidence that suggests there was no zombie attack. It likely was a setup by an unknown, yet, third party.
You bring this evidence back to your Master, who waits at the gates, but he won't let back into the settlement - for your own safety. The people in there have gone past listening to reason and killed your parents pretty much as soon as you left.
So, you find yourself a slave, unofficially freed, in a world of uneasy tensions between the humans and the subs. In your journeys you will encounter camps of subs who have freed themselves, as well as camps of humans of various alignment.
And, possibly, in the second act, real zombies will show up as well. Pulling a Warcraft 3 on everyone.
That's what I have for now
