NuclearSnow and Myself made this map, 100% custom! Try to survive as long as you can and fin the two secret chests! The little house picture is where u hold up in your quest for survival but u need to get to it first. Best goes with The Last Days texture pack witch does need mcpatcher, trust me without it looks gay!
