Okay, I'm testing out a concept of forced cooperative survival. here's the jist of it:
Basic map. One route only accessible by minecart, due to large fall height which would normally kill. Leads to a room which opens up a larger area of the map. Route to basic map part reachable by a large drop into large underground lake, situated near minecart dropoff building.
Extra map parts: Contain several locked doors to several new areas. Activated by a one-off sacrificial chamber nearby, where someone will have to die in order to allow everyone else to survive with all the appropriate tools. Sacrifice also opens up easy-access surface route.
Pros: Means that the survivors have to work cooperatively to survive, or they can all act like dicks and get decimated.
Cons: Time consuming, people and dickishness ensuing, also allows hunters to gain easy access, etc.
