Survive is a first person zombie survival shooter set in a procedurally generated open world. The idea of the game is what would you do in the zombie apocalypse. You are put in a random house in a huge completely procedurally generated world. You have to explore the procedural world to find the food, water, and guns you will need to survive the zombie horde.
This game should not be on sale as it is not a game in any shape or form. The developer doesn't reply to tweets nor does he update. I would stay away until something is actually made. The price is simply a bad joke.
