Caved In is a minecraft custom map contest being run by Project Minecraft. The idea is simple. Download the official PMC Caved In Contest Map and customize it to the best of your abilities, creating something scary, something exciting, or something beautiful. You must start with the official PMC map download and your structures must remain entirely underground. You are free to expand the map as you please, so bedrock truly is the only limit.
Every custom map will be evaluated on three criteria: Originality, Execution and Presentation. Design something mind blowing, pull it off flawlessly and present it in a way that makes people download it with all the compulsion of a sugar addict who just spied a cookie. Simple, right?
