Here is another Survival Games map we use on our Server, there is a radius of 100 blocks, this was again built by the BuildTeam and is full of chests also, there is room for upto 16 tributes.

The houses do not have any interiors so you can fill these in as you please,

The chests are also empty because we fill them through a plugin.

This map is [and always will be] free to download! As long as you give us some credit! 
Please diamond this and share it if you like it :P
