I was playing on my Lost City of Andralis map, and saw that it has a lot of space, and so I decided to make a Paintball Edition :D This Map is powered by command blocks, and so, unless you make it work with a plugin, you can open this world and make it work in vanilla Minecraft, without any mods :D

Features:

-Command Block powered, no mods required :D

-Four teams, Blue, Red, Green and Yellow

-Chests hidden throughout the map containing special items such as Ender Pearls!

Cons:

-Issue with Mobs, I placed as many torches as possible, and lit the cave up as much as possible. (although I guess it adds an extra challenge :D) I reccomend if your putting this on a server, make it a peaceful difficulty area ;)

Tips/Recommendations:

-Currently it uses bows and 2 stacks of arrows for weapons (along with a wood sword for "knifing") If you put in a plugin for paintball that uses snowballs instead, remove the command blocks that give the bow and arrows, or just all command blocks period.

-Keep players in ADVENTURE mode to prevent "cheating" by way of block destruction

-I recommend NOT using a plugin, as it would create more work for you :/ I recommend keeping it at the vanilla state
I made it at, just for convienience and saving of work ;)

Well, that's all for now, cya later guys :D

Additional Notes
