This is xEWOKxButter's CAPTURE THE WOOL map.

Objective is simple:
2 teams, Team Brick and Team Stone.
Use any means to get the other teams wool (this excludes hackers/moders).
There are TNT cannons.
Hidden Chests that can turn the tide of battle.
2 castles, castle brick and castle stone.
4 cannon towers. 2 for brick 2 for stone.
Sandbag areas, so you can hit people with a bow and then hide.
Random River, House, and Pond.
2 different way's to go when you spawn.
Chests loaded with items to repair your castle, repair your cannon, and make your own cannons.

Rules:
No Cheating.
TNT can only be used in the cannons.
You can use the base repair materials to make a TNT cannon wherever you want.
Do not leave the arena, most likely you will die.
You can break anything but iron doors. Unless TNT blows up the door.
You must return the Green Wool to Blue base, and the Blue Wool to Green base to win, the white wool does not count.
If you have the GREEN or BLUE wool on you, you must have it out in your hand.
You can make up any other rule.

Instructions for the TNT cannon are on the TNT cannons in the map. I'll go over them anyway.
1. Place 1-4 TNT above the water, the more TNT the farther it will go.
2. Place 1 TNT above the ladder, this is the projectile.
3. Hit the LEFT button to ignite the ones above the water. CAUTION HITTING THE RIGHT BUTTON MAY RESULT IN DEATH AND DESTRUCTION.
4. wait 2-5 seconds... (five seconds works best :P)
5. Quickly hit the right button to ignite the projectile.
6. Sit back and wait.
7. IT EXPLODES!
8. Repeat.

This explains it better than the signs on the cannons.
