Yaaay, a new map. I'll start uploading different maps for different minigames soon :] I'm also gonna add a bunch of cool command block stuff to all of my 1.8 maps in the near future ;] 
-------------------------------------------------- 
This is a map I made for Skywars. I did not create Skywars, I just made this map. 

IMPORTANT: This map must be used with Minecraft version 1.8 and up. 

Skywars is a mini game. It's kind of like the Hunger Games and Skyblock mixed together.
You spawn on little islands that are located in the void, or somewhere high enough off the ground that you die when you fall. The island you spawn on usually has chests with resources you can use to kill the other players or get to their islands. There is a middle island with chests and resources. Around the map, there are sometimes more chests with things in them. The last one alive wins. 

My map is meant for 4 people. At least 2 players are needed to play. You spawn on 1 of the 4 islands available. There are several chests hidden on those 4 islands. The middle island contains a lot of upgrades for your current armor and weapons, if you have any, such as gold, iron, and diamonds. There are chests around the islands, sitting on small platforms. 

When you first enter the world, you spawn in a rainbow building. In that building, there are 4 pillars in the middle of every side. There are signs on those pillars that say player 1, 2, 3, and 4. Pick what player you want to be and press the button below that sign. You will teleport to one of the islands, on top of the tree. In the building there are 2 additional pillars in the corners closest to the islands. On one, the button gives you a message telling you about what Skywars is and how to play. On the other, it tells you the rules.
