Creating A Dvz

I'm unsure if this server has something similar to this. But its basically like pvp and pve combined. Some servers have this named as dwarfs vs zombies, other servers have it has mass co-op. Basically you defend a block(s) from mobs; or players with disguise on. The objective for the non-mobs is to defend the block/s (often called monument, alter, or statue) and your fellow non-mobs. Most servers have the time for non-mobs winning after the 2nd or 3rd night. While other servers have a ranking system where who survived the longest.

I thought this would be cool to add to this server; if possible, because it would add a gamemode where you would have to look out for other players health while dodging mobs and defending the block/s.
