An idea for a horror story game, you are a "control subject" in a mad scientists lab. After 5 months of being stuck in a cage, you and your cell mates' cages get opened and you have to:
1) Escape the lab
2) Rescue your wife who has been experimented on, you don't know if she's one of the failed experiments (who are the likes of zombies and monsters) or one of the successful experiments (enhanced or superhuman in some way)
3) Kill the scientist (gets you extra points)
Over the course of the game, you're going to have to balance immoral decisions with morality, else you will lose your sanity. If your sanity reaches 0, you become insane and one of the monsters in the lab.
Depending on how many survivors there are at the end, whether you kill the scientist, and how much sanity you have at the end, you will be awarded a certain amount of points.
